Original GitHub issue: https://github.com/open-webui/open-webui/issues/1376

Description

Whenever the API request to the backend takes a while to return any data (usually because the model wasn't loaded yet), and there's a "504 Gateway Time-out" error, the client does not handle it and the user would see the loading skeleton indefinitely, with no indication of a problem unless you open the dev tools.

I suggest adding error handling that'll show a failure message and a retry button to make it clear the request to the backend failed.

I don't know of an easy way to force the backend to return 504 there, for me it happens pretty consistently when loading large LLMs (>20GB) during the first chat message.

I can look into it and create a PR myself when I have some free time (probably later today).
I've seen other response codes are already handled in the UI so it should be a small fix
