    • After configuration nginx revers Proxy no acces to nextcloud (502 Bad Gateway)

      Hi there,

      I am just trying to sercure my Nextcloud and get acces from external.

      I setup Nextcloud in docker with the How To Video of TechnoDadLife at the first step.
      Then tried to get it worked with the second Video HowTo of TDL >

      But at the end I can`t access Nextcloud. Not from external and not from internal anymore.


      502 Bad Gateway


      Portforwarding ist working.
      I get the Letsencrypt Cirtificate in my Browser and can see my SubDomain.


      Does someone have an idea how I can troubleshoot this error? ?(

      Many thanks in advanced.

      Answers in german or russian would be fine too.
