ChatGPT Troubleshooting Guide: Fixing Message Send Failures, Slow Conversation Loading, and Extension Conflicts

If ChatGPT won’t open, messages won’t send, or it keeps spinning, it’s usually not that the “model is broken,” but that your network, browser cache, or extension scripts are interfering. The troubleshooting steps below are organized from fastest to slowest; follow them and you can generally identify the cause and fix the issue reliably.

Start with two quick checks: is the server or the network acting up?

When troubleshooting ChatGPT, first switch to a different network environment to verify: switch from Wi‑Fi to a mobile hotspot, or switch the other way once—this can immediately distinguish between a “local issue” and a “network path issue.” If it recovers immediately after switching networks, it’s likely that the current network’s DNS, proxy rules, or unstable egress is causing request timeouts.

Next, see whether the page can normally load the login and conversation list: if you can log in but can’t send messages, the request is usually being blocked or rate-limited; if even the homepage is stuck, it’s more likely a cache/script conflict. Just doing these two steps can save half the time in many ChatGPT troubleshooting cases.

Message send failures or stuck on “Generating”: check extensions and cache first

If clicking Send does nothing, it stays on “Generating,” or an error appears, the most common cause is browser extensions (ad blockers, script managers, privacy/anti-tracking tools) blocking API requests. The fix is simple: open ChatGPT in an incognito window and log in to test; if it works in incognito, go back to the normal window and disable extensions one by one—check AdBlock, Tampermonkey, and privacy plugins first.

If it still doesn’t work in incognito, then clear cache: clear only the site data related to ChatGPT (cookies/cache), don’t wipe everything at once to avoid getting logged out of other sites. Then log in again and retry—this step is especially effective in ChatGPT troubleshooting for “send failures” and “infinite refresh loops.”

Slow conversation list loading, blank screen, or chats won’t open: check script conflicts and browser engine

If the conversation list is blank or clicking past chats won’t open them, it’s often due to incomplete resource loading or a front-end script error. First, switch browser engines to verify: try Chrome vs. Edge, or open the same account on the mobile web and see whether it still reproduces; if it works after switching browsers, the issue is likely caused by the current browser’s configuration or extensions.

Also, some corporate networks perform HTTPS inspection or content filtering, which can cause intermittent failures in loading static resources. This kind of ChatGPT troubleshooting can be quickly pinpointed by “switching networks + switching DNS”: change DNS to a commonly used public DNS and retry; if it improves noticeably, you can basically confirm it’s a resolution or link-quality issue.

Getting logged out immediately after login or repeated verification: handle account sessions and security policies

If you log in and get redirected back to the login page, or you’re frequently prompted for CAPTCHA, first log out on all devices, then keep only one device logged in to avoid sessions kicking each other out. Having multiple ChatGPT tabs open in the browser can also trigger abnormal sessions; it’s recommended to keep only one chat page open.

If it’s still unstable, finish with the “minimum viable environment” approach in ChatGPT troubleshooting: turn off proxies/traffic-splitting rules, disable all extensions, clear site data, and test by logging in with only one browser and one tab. The goal isn’t to pad steps, but to reduce variables to the minimum—typically the problem will reveal itself at one step and be fixed.
