ChatGPT: "Something went wrong"

It's a generic catch-all error, so it doesn't point to one specific cause. It usually comes from a temporary server hiccup on OpenAI's side, a long or stuck conversation, browser cache/cookies, a browser extension, or an unstable network connection. Because it's generic, the fix is to work through the common causes one by one.

If it happens repeatedly, it's often a single chat that has grown too long or got stuck, a cached/cookie issue in your browser, an extension interfering, or a flaky connection. It can also be an OpenAI-side incident. Start a new chat, try an incognito window, and check status.openai.com to see whether it's their side or yours.

It can be either, which is why you should check status.openai.com first. If OpenAI reports an incident, it's their side and you just wait. If the status page is green, it's usually local — cache, cookies, an extension or your network — and the your-side fixes above should clear it.

Refresh the page, then start a new chat to rule out a stuck conversation. If it persists, open an incognito window to bypass cache and extensions, clear ChatGPT's cookies and cache, and try a different network or turn off your VPN. If status.openai.com shows an incident, wait it out instead.

Often yes. A long or stuck conversation is a common trigger for this generic error, and starting a fresh chat sidesteps it. If a new chat also fails, the cause is more likely your browser cache/extensions, your network, or an OpenAI-side incident.

Yes. Extensions — especially ad blockers, privacy tools and ChatGPT add-ons — can interfere with the page and trigger the generic error. The quickest test is an incognito window, where extensions are usually disabled. If it works there, disable extensions one by one to find the culprit.

If the message starts generating and then fails, it's frequently a connection drop or a very long response timing out, though it can also be a server hiccup. Try again, keep the prompt shorter, check your connection, and see status.openai.com if it keeps happening.

It can. Stale cookies or a corrupted cache are a known cause of the generic error. Clearing ChatGPT's cookies and cache (or simply using an incognito window) often resolves it. You'll need to sign in again afterwards.

If the error is on OpenAI's side, or you just can't clear it quickly, use a multi-model workspace like MultipleChat to switch to Claude, Gemini or another model and keep going for free — then return to ChatGPT once it recovers.
