When using ChatGPT, the most infuriating thing is often not “not knowing how to use it,” but suddenly being unable to send messages, failing to upload images, or being told you’re making requests too frequently. Below is an FAQ that consolidates the most common issues and provides a practical troubleshooting sequence by symptom. You can start checking from the easiest step.
Message send failure: endless loading spinner or an error prompt
If ChatGPT won’t send your message, first refresh the page or restart the app, then resend the same content; many temporary congestion issues can be bypassed right away. If it still fails, it’s recommended to copy the prompt text locally, log out and log back in to avoid a stuck session state.
On the browser side, you can also clear the site’s cache and cookies, and temporarily disable extensions such as ad blockers or script managers; these extensions sometimes block ChatGPT requests. For the network, switch to a more stable connection if possible, and avoid frequently switching networks, which can interrupt requests.
Image upload failure: stuck uploading or “not supported”
If ChatGPT fails to upload images, first check the format and file size: a common approach is to convert the image to JPG/PNG and compress it appropriately, then upload again. If you’re uploading multiple images at once, try validating with a single image first; once it works, gradually increase the number.
If it’s still stuck, switching the upload entry point can also help—for example, use drag-and-drop instead of the upload button in the chat box, or switch to another browser/incognito window. On mobile, make sure the app has permission to access your photo library, and turn off Data Saver/Low Data Mode to avoid the system restricting uploads.
