WebGUI keep asking credentials (OMV 5)

  • Hi guys, after the regular update few days ago I'm not able anymore to access the webGUI with my credentials.

    I have already restarted, cleared the cache, changed the web browser with no results.

    Essentially the login page is not kicking in, no error, just keep asking credientials.

    I can login via SSH and from the console as well.

    I didn't find anything similar with the search but please let me know if it is a known issue and where to find a solution

    Any advise?


    Thanks, MAX

  • Thank you very much.

    I went through the post but I'm a very basic user and I'm stuck to move on.

    Can you help me out?


    Thanks in advance!

  • When you installed docker you put your containers on your OS drive. My guess is, you have plex or emby/jellyfin, and their metadata folders are filling your OS drive.


    You can either...


    1. Start over by deleting /var/lib/docker and then setup all your containers again and make sure that your containers folder is on a storage drive (which Im assuming is much larger)


    2. Move your containers folder and then change the path in the webUI to your new containers location. This has the advantage of keeping your currently configured containers.

    Air Conditioners are a lot like PC's... They work great until you open Windows.


  • I have the same Problem


    WebGui stuck in login loop

  • Thanks KM0201.

    This machine is dedicated to Unifi controller.... i believe something went wrong during the system update. The disk is fairly big for the scope, is there a way to clear the rubbish maintaining the config without adding extra disk?
