ChatGPT Troubleshooting Guide: Fix Ideas for a White Screen, Login Loops, and Endless Loading Spinners

If ChatGPT won’t open, gets stuck loading, or keeps bouncing back to the login page, don’t rush to reinstall your browser. Follow the order below—“rule out server-side issues first, then handle the browser, and finally check the network”—to troubleshoot ChatGPT errors. This usually helps pinpoint the cause and restore access.

Start with a basic ChatGPT troubleshooting check: confirm the service is operating normally

First, it’s recommended to open status.openai.com to see whether there are any issues with login, chat, or file services. When the server side is fluctuating, it’s hard to resolve immediately no matter what you change locally. Also compare whether the same account reproduces the issue on mobile data versus your home network, to judge whether it’s an environment issue or a platform issue.

If the error only occurs on a specific network, prioritize the network and blocking policies as the likely cause; if none of your devices work, continue with the ChatGPT troubleshooting steps below.

Login loop / returning to the login page after verification: most likely cookies or an extension is blocking

The key to troubleshooting this kind of ChatGPT issue is browser data: first sign in using an incognito/private window to see whether it works. If it works there, it indicates an extension or cached data is the cause. Next, clear site data for chatgpt.com and openai.com (cookies/cache/local storage), and temporarily disable ad blockers and privacy/anti-tracking extensions before trying again.

Also check whether the browser is blocking cookies (especially if third-party cookie restrictions are too strict) and whether the system time is set to sync automatically; a large time offset can cause login token validation to fail, making it look like you keep getting sent back to the login page.

White screen / sidebar not loading: from cache and hard refresh to browser compatibility

When troubleshooting ChatGPT, a white screen is commonly caused by old cached scripts or blocked page resources. First try a “hard refresh” (Windows: Ctrl+F5; Mac: Cmd+Shift+R). If that doesn’t work, clear the site cache and reopen it.

If you still see a white screen, quickly verify by switching browser engines: try Chrome/Edge/Firefox. If it opens in another browser, it indicates a configuration issue with the current browser. You can also temporarily disable “hardware acceleration”; sometimes GPU drivers/rendering can cause page components not to display.

Endless loading spinner / send failure: focus on the network and proxy route

For this type of ChatGPT troubleshooting, it’s recommended to start with a “switch network test”: comparing a mobile hotspot with a company/campus network is the most straightforward. Some networks block WebSocket or specific domains, causing chats to spin endlessly or messages to fail sending.

If you’re using a proxy/VPN, try switching nodes or temporarily turning it off and testing again, to avoid split-tunneling rules sending ChatGPT requests over an unstable route. DNS issues can also cause slow loading or resource fetch failures; you can temporarily switch to a reliable public DNS and try again.
