ChatGPT FAQ: White Screen Freezing, Device Verification, and Session Recovery

This article compiles the most common issues encountered when using ChatGPT, including login problems, white-screen freezing, verification failures, and session recovery. Each issue provides a practical troubleshooting order, starting with the easiest and most effective steps.

What to do if you can’t log in and device verification fails

If ChatGPT login gets stuck on the verification page or shows a verification failure, first check whether your system time is set to sync automatically—an incorrect time can cause verification codes to expire. Then log in to ChatGPT again using an incognito/private window to avoid old cookies interfering with the process.

If you can’t receive the email verification code, first check the spam folder and the “Promotions/Subscriptions” categories, and confirm your mailbox isn’t set to automatically block emails from OpenAI. If it still doesn’t work, switch to a different network environment and trigger the verification code again—often, network risk controls prevent ChatGPT’s verification request from reaching you.

White screen on open, endless loading spinner, or very laggy page

If ChatGPT shows a white screen or keeps loading with a spinner, first disable browser extensions—especially ad blockers, script managers, and privacy/anti-tracking extensions—as these are most likely to block critical resources. Then clear the site’s cache and cookies and refresh the page.

If it only lags on a specific network, switch to a more stable network or change your DNS; also check status.openai.com to see whether ChatGPT is experiencing service fluctuations. If you encounter similar issues on mobile, updating the app and restarting once is usually more effective than repeatedly logging out and back in.

How to troubleshoot messages not sending or “request error” prompts

If ChatGPT shows no response after sending or prompts a request error, first copy your input locally to avoid losing it on refresh. Then reduce the length of what you send at once, remove overly long quotes or large code blocks, and send in segments—this can significantly reduce the failure rate.

If you see frequent request failures or throttling messages like 429, wait a few minutes and try again, and reduce consecutive retry attempts; repeatedly clicking send makes ChatGPT more likely to trigger protective mechanisms. On the browser, you can also try switching to another network before sending to rule out interruptions caused by network jitter.

How to recover missing sessions or incomplete history loading

If the ChatGPT conversation list is blank, first confirm you didn’t switch to a different account (the same email with different login methods may lead you into different account systems). Then try logging out, closing all tabs, and logging in again to let ChatGPT re-fetch your history.

If only a specific conversation won’t open, try opening ChatGPT with the same account on mobile or in another browser to verify whether it’s a local cache issue. If it still can’t be restored, prioritize recovering from saved exports, copied content, or project materials to avoid a single point of dependency on the conversation list.

Common reasons for image/file upload failures

ChatGPT upload failures are mostly related to file size, network interruptions, or browser permissions. First compress images, switch to a more common format, and make sure you don’t switch the app to the background or lock the screen during the upload. If the browser pops up a permission prompt, allow ChatGPT file access and try again.

Corporate networks or public Wi‑Fi may block upload domains, causing the progress bar to get stuck; switching to a mobile hotspot often immediately confirms the cause. If failures happen frequently, consider sending a text summary first, then add attachments in multiple batches to reduce the risk of a single request.
