Since one month my Windows-Client failed after a random time to login in my Nextcloud. That happens once a week, so that I must reauthorized the client via my browser.
This behavior has worsened in the past few weeks. At the moment I must re-authenticate every 5 minutes or after an hour. This happens on several PC’s. Sometimes I also can’t login via the Browser Chrome and must switch to Firefox.
In the Nextcloud Log are no useful information printed:
Warning by trying to login with the Windows-Client:
{"reqId":"XXX","level":2,"time":"2020-04-08T21:14:26+00:00","remoteAddr":"XXXX","user":"User","app":"core","method":"GET","url":"/index.php/login/v2/flow/XXXX","message":"Renewing session token failed","userAgent":"Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/80.0.3987.163 Safari/537.36","version":"18.0.0.10"}
Warning by trying to login with the Browser:

Here you can see, that Nextcloud opens a new session every time.
