What started as excitement about what DeepSeek can do has now turned into frustration about why it’s not doing anything at all. And if you’ve run into that ominous browser warning—

So… What’s Really Going On?

After receiving a flood of messages from DeepSeek users, our team took a deep dive into the issue, and it turns out, this isn’t just a random glitch. DeepSeek’s platform and APIs have been under a major malicious attack. In response, they’ve temporarily paused new sign-ups, though existing users should still be able to log in without too much trouble.

Some of the error messages might also be due to heavy traffic spikes. The system can’t keep up when too many people try to use the service at once.

The DeepSeek team is on it, monitoring things behind the scenes and actively working to bring everything back to normal. Hopefully, we’ll see full service restored soon.

Other Common DeepSeek Errors (And How to Fix Them)

If you’re dealing with something other than the main website error, here are a few other issues people have reported—and how to solve them.

🔹 Error 400: Something’s Off With the Data

This error usually means DeepSeek can’t make sense of what you’re sending it.

Why it might be happening:

The format of your request (JSON or XML) is broken—maybe a missing bracket or a typo.
You didn’t include all the required info.
You sent the wrong data type (e.g., a string instead of a number).
The file you uploaded isn’t supported, or it’s corrupted.

Try this:

Double-check the format of your JSON or XML using a validator tool.
Make sure all required fields are filled out.
Match the data type to what DeepSeek expects.
Clear your browser cache, and double-check the URL for typos.

🔹 Error 401: Access Denied

This one’s about authentication—usually tied to your API key or token.

What could be wrong:

Your API key is missing, expired, or just wrong.
The key is formatted incorrectly.
Your key doesn’t have the right permissions.

Fix it by:

Making sure the key is correct and hasn’t expired.
Requesting a fresh key if needed.
Checking your username and password for errors or extra spaces.
Formatting your authorization header correctly (e.g., Authorization: Bearer your_token_here).

🔹 Error 500: Something Broke on Their End

If you’re seeing a 500 error, chances are it’s not your fault—it’s a server-side problem.

Possible reasons:

DeepSeek servers might be overloaded.
There could be a backend bug or glitch.
Your browser’s cached data is causing issues.
Check DeepSeek’s status page

What you can do:

Refresh the page—sometimes that’s all it takes.
Clear your cookies and cache.
Try a different browser or device.
Disable browser extensions just in case one’s interfering.
Check DeepSeek’s status page to see if it’s a known issue.

🔹 Error 503: Server Too Busy

This one’s pretty self-explanatory: too many users at once, or the system is under maintenance.

Why you might see it:

DeepSeek’s user base has exploded, and the servers can’t keep up.
The platform is being updated or maintained.
You’re on a weak or unstable internet connection.
Your browser has old or buggy cache data.

Quick fixes:

Switch to a faster or more reliable connection.
Refresh the page with Ctrl + F5 or Command + Shift + R.
Clear cookies and cached files from your browser.
Try incognito mode or a different browser/device.
Flush your DNS cache if you’re on a desktop.

The Most Common Issue Right Now: “Server is Busy. Please Try Again Later.”

Lately, this is the message most users are seeing. It’s not a standard error code like 500 or 503—it’s a custom alert triggered when DeepSeek is under too much pressure.

In most cases, this happens when:

Too many users are on at once (especially with version 3)
Malicious activity is overwhelming the servers
You’re trying to connect from a region where DeepSeek isn’t currently supported

Here’s how to deal with it:

Refresh or restart: If you’re on the website, hit refresh. If you’re using the app, fully close and reopen it.
Check DeepSeek’s server status: Use their official status page.
Try a stronger internet connection: Switch between Wi-Fi and mobile data if needed.
Change browser or device: If one doesn’t work, try another.
Use a VPN: DeepSeek isn’t available in every country. Try accessing it from a supported location.
Contact support: If nothing works, reach out for direct help.
