Web Control Panel login with correct credentials suddenly not working

1. offizieller Beitrag

    Suddenly, I cannot login to the Web Control Panel. (At the same time ssh is no problem.)

    Credentials are correct (I am using Lastpass to auto fill the form fields). To be sure I have double checked and tried it manually as well.

    The Login seems to work (no errors) but after a few seconds the Login screen is shown again. It is in a loop.

    FYI: When I intentionally use a wrong password I get the usual red error message


    What I've tried to fix it:

    1)

    omv-firstaid:

    3 Change control panel administrator password

    4 Reset failed login attampts


    2)

    apt-get update && apt-get upgrade


    3)

    sudo reboot


    No success ;(


    What I suspect caused it:

    The last time I was logged into the web panel I was using the "Update Manager".

    I think the "upgrade" did not work. Unfortunately I can't recall the details.

    After that the problem happened.


    When I do this via ssh I get the following:

    Code
    apt-get update && apt-get upgrade
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

    In the shell run df -h and see if the rootfs is full or not.

    I still can't login to my web control panel.


    Here is a short video-capture of 2 login attempts with correct PW and a final one in contrast with an incorrect PW:

    Samba shares work fine.


    Code
    omv-firstaid:

    Points 2 - 10 all work and confirm everything is valid

    Point 11 "Submit diagnostic report to administrator" is attached.


    Code
    apt-get update && apt-get upgrade

    worked with no errors


    Code
    omv-update
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

    I regularly used first-aid to "Reset failed login attempt counter".

    Solved my issue with duffr's answer:

    chmod 777 /var/lib/php/sessions


    Thank's votdev for pointing me to the logs! That was quite helpful!


    FYI

    On a cloned SD Card I also solved it with hugn's answer (which basically does the same to the "sessions" directory):

    sudo rm -rf /var/lib/php/sessions

    sudo mkdir -m 777 /var/lib/php/sessions

    ls /var/lib/php -l

    sudo nginx -s reload
