When Perplexity stops working, it usually shows up in one of a few ways: the page sits on a loading spinner, an answer starts generating and then stalls, you get an error message instead of a response, or the app refuses to sign you in. Because Perplexity is an answer engine that searches the live web and then summarizes sources, it has more moving parts than a plain chatbot, and that means there are more places where things can hiccup. The good news is that most of these problems fall into a handful of categories, and most are quick to diagnose.
This guide walks through how to tell whether the issue is on Perplexity’s side or yours, the most common causes, and the fastest fixes for each. Before you spend time troubleshooting your own setup, the single most useful first step is to check the live Perplexity status page. If our monitoring already shows Perplexity as degraded or down, you can skip straight to the bottom of this guide and just wait.
First: Is it Perplexity, or is it you?
The fastest way to save yourself effort is to figure out which side the problem is on before you start changing settings. If Perplexity is having a real outage, nothing you do on your device will fix it, and there is no reason to clear your cache five times.
Start with the Perplexity status page on is-down.ai. It shows the current real-time status, recent uptime history, and crowd-sourced reports from other users. If reports are spiking and the verdict says something is wrong, the problem is almost certainly on Perplexity’s end. If the status shows everything operational but you still cannot connect, the issue is more likely local to your device, network, or account.
A few quick cross-checks that take seconds:
- Try a different network. Switch from Wi-Fi to mobile data, or vice versa. If it works on one but not the other, the problem is your network, not Perplexity.
- Try a different device. If the web version works on your phone but not your laptop, the issue is on that one device.
- Try the other surface. If the app is failing, open Perplexity in a browser, or the reverse. A problem that only affects one surface points to that app or browser rather than the whole service.
For a deeper walkthrough of this diagnostic logic, see our guide on how to tell if an AI service is down or it’s just you. The whole live picture for every tool we track is on the is-down.ai dashboard.
Common causes and how to fix them
1. Server load and high demand
This is the most common reason a working service suddenly feels broken. When a lot of people hit Perplexity at once, or when something upstream is straining, you may see slow answers, timeouts, half-finished responses, or generic error messages. None of this is something you caused, and none of it is fixable from your end.
What to do: check the status page for a spike in reports. If demand is the issue, give it a few minutes and try again. Retrying the same query repeatedly during a busy period can make things worse, not better, because each retry adds to the load. Wait, then send one clean request.
2. Account, sign-in, or subscription issues
A surprising number of “Perplexity is not working” moments are really sign-in problems. If your session has expired, if you are logged into the wrong account, or if there is a billing hiccup on a Pro subscription, the interface can behave as though the whole service is down when it is only your account that is affected.
What to do: sign out completely and sign back in. If you use Pro features and they suddenly stop, confirm your subscription is still active in your account settings and that your payment method has not lapsed. If you signed up through a third party (an app store, or a single sign-on provider like a Google or Apple login), make sure that connection is still valid. If you cannot sign in at all and the status page is green, the problem is almost certainly account-side, not service-side.
3. Rate limits
Perplexity, like most answer engines, limits how many requests you can make in a given window, and the limits differ between free and Pro tiers and between modes. If you have been firing off a lot of queries quickly, or leaning heavily on the more advanced research modes, you can hit a cap. The symptom is usually a message telling you to wait or upgrade, or answers that quietly stop coming.
What to do: slow down and wait for the limit to reset, which typically happens on a rolling basis. If you regularly hit limits on the free tier, that is by design, and the fix is either to pace your usage or upgrade. A rate limit is not an outage, so the status page will look perfectly healthy while it happens.
4. Source-fetching and search hiccups
This one is specific to answer engines. Perplexity does not just generate text, it searches the web, retrieves pages, and cites sources. That means it depends on being able to reach other sites in real time. If a source is slow, if a page blocks automated retrieval, or if the search step stalls, you can get an answer that is missing citations, a response that cuts off, or an error even though Perplexity’s core service is technically up.
What to do: rephrase your question or try a slightly different topic. If a specific query fails repeatedly but other queries work fine, the problem is likely tied to the sources for that one topic, not to Perplexity as a whole. Switching modes (for example, a simpler search instead of a deep research run) can also get you a result when the heavier path is struggling.
5. Browser cache, cookies, and extensions
If Perplexity loads but behaves oddly in your browser, answers won’t render, buttons don’t respond, the page looks broken, stale cached files or a misbehaving extension are common culprits. Ad blockers, privacy extensions, and script blockers are especially likely to interfere, because they can block the very scripts the page needs to function.
What to do, in order:
- Hard refresh the page (Ctrl+Shift+R on Windows or Cmd+Shift+R on Mac).
- Open Perplexity in a private or incognito window. If it works there, an extension or cached data is the cause.
- Disable extensions one at a time, or whitelist Perplexity in your ad blocker and privacy tools.
- If it still misbehaves, clear cookies and cached files for the site, then sign in again.
- Try a different browser entirely as a final check.
6. The app versus the web version
The mobile and desktop apps and the website can fail independently. An app can break after an update, run into a stale local cache, or hold onto an expired session, while the website works perfectly, or the reverse.
What to do: if the app is failing, force-close it and reopen it. Check your app store for a pending update, since running an outdated version is a frequent cause of strange behavior. If that does not help, sign out and back in, or remove and reinstall the app. Meanwhile, the web version is a reliable fallback that lets you keep working while you sort the app out.
7. Regional and network problems
Sometimes Perplexity works fine for most people but not in your region or on your particular connection. This can be caused by a regional routing problem, a corporate or school network that filters certain services, a VPN that is sending your traffic through a blocked or congested path, or local DNS trouble.
What to do: turn your VPN off and try again, since a VPN exit point can be the thing being blocked or throttled. If you are on a managed network at work or school, that network may be filtering the service, so test on mobile data to confirm. Restarting your router and switching your DNS to a well-known public resolver can resolve stubborn local connection issues. If only your region seems affected and the global status looks healthy, it may be a localized routing problem that clears on its own.
A quick step-by-step when Perplexity won’t work
If you want a single sequence to run through, do this in order and stop as soon as it works:
- Check the live status page. If it is down, stop here and wait.
- Hard refresh the page or force-close and reopen the app.
- Try incognito mode or a different browser to rule out cache and extensions.
- Switch networks (Wi-Fi to mobile data) and turn off any VPN.
- Sign out and back in to refresh your session.
- Wait a few minutes and retry once if you suspect high demand or a rate limit.
- Rephrase your query or change modes if one specific question keeps failing.
If you have run through all of these and it still does not work, and the status page is green, the issue is narrow enough that waiting a short while and retrying is usually the right move. Services often resolve transient glitches on their own.
When to just wait
Some problems are simply not yours to fix. If the status page shows an active outage, if reports are spiking from many users at once, or if a query that normally works fails everywhere you try it, the smartest thing to do is stop troubleshooting and wait. Repeatedly retrying during an outage adds load and rarely helps.
While you wait, you don’t have to be stuck. Our guide on what to do when an AI tool is down covers how to stay productive, including reliable alternatives you can switch to for the moment. And if you want to keep an eye on more than one service at a time, the is-down.ai dashboard shows the live status of every AI tool we monitor in one place, so you can see at a glance whether the problem is isolated to Perplexity or part of something broader.
Most of the time, “Why is Perplexity not working?” has a calm answer: a busy moment, an expired session, a cached file, or a network quirk. Work through the checklist, lean on the live data, and you will usually have it sorted in a few minutes, or know for certain that the only thing left to do is wait.
Frequently asked questions
How do I know if Perplexity is down for everyone or just me?
Check the live Perplexity status page at Perplexity on is-down.ai. It shows real-time status, uptime history, and crowd-sourced reports from other users. If reports are spiking and the verdict shows a problem, it is down for many people. If the status is green but you still cannot connect, the issue is likely your device, network, or account. A quick way to confirm: try Perplexity on a different network or device, and if it works there, the problem is local to you.
Why does Perplexity load but not return any answers?
This usually points to one of three things: high demand or server load causing timeouts, a rate limit if you have sent many queries quickly, or a source-fetching hiccup since Perplexity searches the live web and depends on reaching other sites. Try waiting a moment and sending one clean request, rephrasing your question, or switching to a simpler search mode. If the status page shows an active outage, the cause is on Perplexity’s side and waiting is the only fix.
Why can't I sign in to Perplexity even though it isn't down?
Sign-in failures are usually account-side rather than service-side. Your session may have expired, you may be on the wrong account, or there may be a billing issue with a Pro subscription. Sign out completely and back in, confirm your subscription and payment method are active if you use Pro, and check that any third-party login (such as a Google or Apple sign-in) is still connected. If the status page is green, the problem is almost certainly with your account, not the service.
Perplexity works in my browser but not the app. What should I do?
The app and the website can fail independently. Force-close the app and reopen it, then check your app store for a pending update, since running an outdated version is a common cause of odd behavior. If that does not help, sign out and back in, or reinstall the app. In the meantime, the web version is a reliable fallback so you can keep working while you fix the app.
Should I keep retrying when Perplexity is down, or just wait?
If the status page shows an active outage or reports are spiking from many users, just wait. Repeatedly retrying during an outage adds to the load and rarely helps, and the issue is not something you can fix from your end. While you wait, our guide on what to do when an AI tool is down covers reliable alternatives, and the is-down.ai dashboard lets you watch for recovery across every service we monitor.
