Describe the Bug
When a request is made it throws an error. It still works but can fill the logs.
Something to note is that llm container has this log every few seconds:
2026-01-14 08:00:47,650 - urllib3.connectionpool - WARNING - Retrying (Retry(total=0, connect=None, read=False, redirect=None, status=None)) after connection broken by 'MustRedialError('Remote peer just closed our connection, probably for not answering to unsolicited packet. (None)')': /ocs/v2.php/taskprocessing/tasks_provider/next?format=json
and stablediffusion2 container gives this:
2026-01-14 08:04:47,645 - main - ERROR - Remote end closed connection without response
So maybe it is all related?
P.S. Sorry for not giving better logs. I am not sure what is helpful, what is sensitive information, and what would just get in the way of what you need.
To Reproduce
Make a request to do an ask context chat, it seems to work with the search so just the "context chat" in Assistant.
PHP logs (Warning these might contain sensitive information)
No response
