    Hi all!
    Yesterday I upgraded my server. After the upgrade my libreNMS started to notify me about 421 Misdirected Request error. I could not find the problem, everything looks okay, I tried website checkers non of them displayed error.
    My apache version after the upgrade: 2.4.65-1~deb11u1

    The website which drops the error: https://harry-sopron.freeweb.hu/

    Can anyone confirm me the 421 error or I just chasing ghosts?

    I can copy the vhost file of the website:
