ChatGPT has had a rough few weeks. OpenAI's own status history shows elevated error rates for ChatGPT Pro and Plus users on 30 September 2026, login and sign-up problems on 1 October, and degraded conversation performance again on 5 October. When the chatbot half your workflow depends on starts failing, the first question is always the same: is it down, or is it me?
This guide answers that in the first fix, then walks through 8 proven solutions for every common ChatGPT failure — the dreaded "Something went wrong" banner, "Error in message stream", login loops, and the mobile and desktop apps refusing to cooperate. Work through them in order; each one takes under two minutes.
First: is ChatGPT down right now?
Before you touch a single setting, check status.openai.com. If ChatGPT shows "Degraded Performance" or "Partial Outage", no fix on your end will help — the problem is on OpenAI's servers and you just have to wait. Downdetector's ChatGPT page is a useful second opinion: a sudden spike in reports confirms a widespread incident.
If the status page is all green and you're still getting errors, the problem is local — and one of the 8 fixes below will almost certainly sort it.
8 proven fixes for ChatGPT not working
Fix 1 — Hard-refresh and restart the session
A surprising share of "Something went wrong" errors are nothing more than a glitched session. In your browser, press Ctrl + Shift + R (Cmd + Shift + R on Mac) to force a full reload that bypasses the cache. If you use the desktop or mobile app, force-close it completely and launch it again, then send your message in the fresh session.
Fix 2 — Start a new conversation (fixes "Error in message stream")
Seeing "There was an error generating a response" / "Error in message stream"? That error almost always means the current conversation got corrupted mid-stream — your account and connection are fine. Click "New chat" and send the same prompt again. If it works there, the old chat is the problem; long conversations with very long responses break most often, so keep prompts and outputs in manageable chunks.
Fix 3 — Clear ChatGPT's site data, cookies and cache
Corrupted stored data is a classic cause of ChatGPT not loading and of pages that spin forever at login. In Chrome, open chrome://settings/content/all, search for chatgpt.com, and delete its stored data — this removes cookies and cache for ChatGPT only, without logging you out of other sites. Then sign back in. On other browsers, clear cookies and cached images from the privacy settings.
Fix 4 — Disable your VPN, proxy and real-time web protection
This is the single biggest cause of ChatGPT failures that people overlook. VPNs and proxies routinely trigger "We detect suspicious activity" messages and failed logins, because the traffic comes from flagged IP addresses. Equally, security tools with real-time web protection — built into many VPN clients, antivirus apps and even some browsers — interfere with ChatGPT's traffic in ways that produce the vague "An error occurred" message. OpenAI has specifically flagged NordVPN's Threat Protection feature as a culprit.
- Temporarily disconnect your VPN or proxy and retry ChatGPT.
- Turn off Threat Protection / web shield / real-time protection in your VPN or antivirus app, then reload.
- If that fixes it, re-enable protection afterwards and add chatgpt.com as an exception instead of leaving yourself unprotected.
Fix 5 — Sign out and back in; break the login loop
Session tokens expire or corrupt silently, which is why logging out and signing back in fixes errors that nothing else touches. If the login page itself spins forever, open an incognito/private window and sign in there — if it works, a browser extension (especially ad blockers and script blockers) is interfering in your normal profile.
One more hidden cause of login failures: clock drift. If your device's date and time are wrong, the secure connection handshake fails. On Windows, go to Settings > Time & language and make sure "Set time automatically" is on; on phones, check Date & time in Settings.
Fix 6 — Update or reinstall the ChatGPT app
If ChatGPT won't open, is stuck on the splash screen, or chats won't sync on your phone or PC:
- Windows app: open the Microsoft Store, go to Library and install updates. If it's still broken, uninstall the app, delete any leftover app-data folders, and reinstall the latest build from the Store.
- iPhone / Android: update the app from the App Store or Play Store. On Android you can also clear the app cache (Settings > Apps > ChatGPT > Storage > Clear cache); on iPhone, offloading and reinstalling achieves the same.
Quick diagnostic: if chatgpt.com in the browser works but the app doesn't, the bug is app-side, not your account. Use the browser version until OpenAI ships a patch.
Fix 7 — Try a different browser or device
If ChatGPT fails in Chrome but works in Edge, Firefox or Safari, your browser profile is the problem — usually an extension or a corrupted cache (see Fixes 3 and 5). Switching networks helps too: hop from Wi-Fi to mobile data, or vice versa, to rule out router, firewall or ISP-level blocks on OpenAI's servers.
Fix 8 — Slow down: rate limits and account flags
"Too many requests" means exactly what it says — you've hit OpenAI's usage limits, especially common on the free tier. Wait about an hour for the limit to reset, send shorter prompts, and leave pauses between requests. "We detect suspicious activity" is an account flag: stop using shared logins, disable any VPN (Fix 4), and retry. If your subscription shows as active but paid features still don't work, contact OpenAI support — that's a billing-side problem no local fix can solve.
When none of this works
Wait 30–60 minutes and try again — server-side incidents like the October 2026 conversation-error wave resolve on OpenAI's side, not yours. And if outages keep interrupting your work, it's worth keeping a backup AI in your toolkit: our guide to 5 strong alternatives covers free options that work when ChatGPT doesn't.

Frequently asked questions
Why does ChatGPT keep saying "Something went wrong"?
This generic error usually means a temporary server issue, a broken session, or corrupted browser data. Hard-refresh the page, clear ChatGPT's site data, start a new conversation, and check status.openai.com to rule out an outage.
Is ChatGPT down right now?
Check status.openai.com for the live state of ChatGPT, the API and logins. OpenAI reported degraded conversation performance on 5 October 2026 and login problems on 1 October 2026, so if your errors cluster around those windows, an incident was likely the cause.
What does "Error in message stream" mean on ChatGPT?
It means the connection carrying ChatGPT's response was interrupted — most often a corruption in that specific conversation rather than your account. Open a new chat and resend the prompt; shorter prompts break less often.
Why is ChatGPT not working on my phone but works on my computer?
That's an app-side problem, not an account problem. Update the mobile app, clear its cache (Android) or reinstall it (iPhone), and disable any VPN on the phone. The browser version at chatgpt.com works as a full substitute.
How do I fix the ChatGPT login loop?
Sign out everywhere, clear chatgpt.com cookies, and sign in through an incognito window to rule out extension interference. If the loop persists, disable your VPN and make sure your device's clock is set to automatic — clock drift breaks the secure login handshake.
Why does ChatGPT say it detected suspicious activity on my account?
OpenAI flags traffic that looks automated or unusual, most commonly from VPN or proxy IP addresses, or from logins shared across many people. Disconnect the VPN, use a private window, stop sharing the account, and try again.
