If DeepSeek just stalled, froze on a reply, or refused to load, you are in the right place. The good news is that most problems with DeepSeek are quick to pin down, and many of them are not even on DeepSeek’s side. A few simple checks will usually tell you whether the service itself is having trouble or whether something on your device or network is getting in the way. Below is a calm, practical walkthrough you can follow in a couple of minutes.
Common reasons DeepSeek stops working
DeepSeek publishes the web chat and the API as separate components, and they fail independently. Reading the right one keeps an API-only incident from looking like a web-chat outage.
- Web chat versus API. The chat at chat.deepseek.com and the developer API at platform.deepseek.com are separate services on DeepSeek’s own status page. If your API calls fail, the web chat can still work, and the reverse is true too.
- “The server is busy.” This message on the web chat is a capacity signal during heavy demand, not proof of a full outage. Waiting a short while and retrying is usually enough.
- API keys and rate limits. On the API a 401 or 403 points to a key or permission problem, and a 429 means you have hit your rate limit. These are account-side and happen even when the platform is healthy.
- Sign-in and your connection. An expired session, or a network or VPN routing issue, can block the web chat while the service itself is reachable for others.
How to fix DeepSeek when it is not working
Work through these steps in order. Most people are back up and running before the end of the list.
- Hard refresh the page. Reload with the cache bypassed (Ctrl+Shift+R on Windows or Linux, Cmd+Shift+R on a Mac). This clears a surprising number of loading and freezing glitches.
- Open a private or incognito window. A private window ignores your extensions and cached data, so it is the fastest way to tell whether the trouble is local. Sign in to DeepSeek there and see if it behaves.
- Sign out and back in. If you see login loops or permission errors, log out fully, then sign back in to refresh your session.
- Clear your cache and cookies. If a private window worked but your normal window did not, clear DeepSeek’s cached files and cookies in your browser settings, then reload.
- Switch networks. Move from Wi-Fi to mobile data, or the reverse. If DeepSeek works on one network but not the other, the problem is your connection or local routing, not the service.
- Disable extensions and your VPN. Turn off ad blockers, privacy add-ons, and any VPN or proxy, then try again. Re-enable them one at a time to find the culprit.
- Update or restart the mobile app. On a phone, fully close the app, check the app store for an update, and reopen it. A device restart clears lingering connection issues.
- Wait out rate limits. If you have been sending many messages, pause for a few minutes. Limits usually reset on their own, and the assistant starts responding again without any further action.
Is DeepSeek down, or is it just you?
The quickest way to separate a real outage from a local hiccup is to test from more than one angle. First, check the live verdict and the recent reports at the top of this page. If many people are reporting trouble at the same time, the issue is very likely on DeepSeek’s side and the fix is simply to wait.
If this page shows DeepSeek as healthy, the problem is probably closer to home. Open a private window and try a different network, such as switching from Wi-Fi to mobile data. If DeepSeek works in either of those, you have found the cause: an extension, a cached file, or your usual connection.

How we check DeepSeek
We determine DeepSeek’s status from two signals rather than guessing. First, we read DeepSeek’s own official status page, which reports the web chat service and the API service as separate components; only the web chat component drives the main verdict, and an API incident is shown in its own group without marking the web chat down. Second, we run our own independent reachability check against the service so we can catch problems even before they are officially acknowledged. When those two signals disagree, we lean toward what real users are actually experiencing. You can read more about how this works on our methodology page.
Alternatives to DeepSeek during an outage
If DeepSeek is down and you need to keep working, it helps to have a backup assistant ready. Any of these can handle most everyday tasks while you wait for DeepSeek to recover.
- ChatGPT is a widely used general-purpose assistant that covers writing, coding, and questions of all kinds.
- Claude is a strong choice for longer documents, careful reasoning, and detailed writing help.
- Gemini works well for research-style questions and tasks tied into other everyday tools.
It is worth keeping an account with at least one of these so an outage never leaves you stuck. Once DeepSeek is back, you can switch straight back to it. And if you are unsure whether DeepSeek has recovered, return to this page for the current verdict before retrying.
How DeepSeek outages usually show up
DeepSeek runs two separate things that fail in different ways: the chat web app and mobile app at the consumer end, and the developer API. The most common consumer symptom is a reply that stalls and returns “The server is busy. Please try again later.” during peak demand, which often spikes when a new model lands and traffic surges. The reasoning mode can also start a response, show its thinking, and then cut off before the final answer arrives.
Because DeepSeek’s infrastructure is based in China, users far from those servers sometimes see slower first-token times, timeouts, or connection failures that look like a full outage but are really latency or regional filtering. The web app and the API have independent capacity, so the developer endpoints can keep returning 503 or 429 responses even while chat looks healthy, or the reverse.
- Web or app stuck on “server is busy” or a spinning response
- Sign-in or verification code emails not arriving
- API returning rate limit or service unavailable errors
- High latency or blocked connections from certain regions
