I’m struggeling with this issue for a long time now without any solution.
My nextcloud server is running as docker container, with nginx-proxy and proxy-companion for letsencrypt certificates.
Unfortunately the server keeps logging out all users regularly unconditionally.
Looking to the server logs, the only thing I find is that everything’s working find but suddenly it starts logging this error:
"Exception": "Sabre\\DAV\\Exception\\NotAuthenticated",
"Message": "No 'Authorization: Basic' header found. Either the client didn't send one, or the server is misconfigured, No 'Authorization: Bearer' header found. Either the client didn't send one, or the server is mis-configured"
This happens on all clients, no matter if it’s the windows client, Android or iOS client. So I am sure it’s no client issue.
I recorded a session on my laptop with fiddler. This shows to me that from the one second to the other 401 errors are returned - I cannot determine why.
As you can see in the screenshot, there are many PROPFINDs answered with 207 and suddenly it turns to 401:
Looking to the request headers it’s visible that absolutely nothing regarding authorization etc. changed from the last working request to the denied request. There is a Basic auth header present which doesn’t change from the last working to the denied request.
This is the respective log entry of the given first 401 report:

After a re-login, it’s working for some time but then - after a unpredictable time - the users are thrown out again.
Do you have any idea what could be happening here?
