ONLYOFFICE certificate error?

Dear Community,
since a while my ONLYOFFICE isn’t working correctly anymore. If klick to open an excel file (same with doc and docx) it opens a landing page in my browser which trys to lead me to the specific Link [Picture_1]. Klicking on the button „open page in new tab“ it opens the ONLYOFFICE Page [Picture_2]. I expect to open the file but there is just a blur/empty ONLYOFFICE-page.

Can you help me guys, plz? Or do you have a hint for me?

Some may-be-important information:

  • ONLYOFFICE is installed on docker
  • Document server is running by calling www.onlyoffice.mypage.de
  • Calling my IP xxx.xxx.xxx.xxx:4433 it gives me the error „400 Bad Request - The plain HTTP request was sent to HTTPS port by nginx“ [Picture_3]

Update-Change-log:

  • I updated from PHP 7.2 to 7.4
  • From NC 17 to NC 19.4
  • Changed to 4-Bit Support (also changed collates in msql database)

What I tried so far:

  • New generation of a new certificates self signed in docker image (/app/onlyoffice/DocumentServer/data/certs)
  • New Generation of all Lets-Encrypt Certs
  • Checked the /var/www/nextcloud/config/config.php fort he array: verify_peer_off’ => true
  • Reinstalling the container via docker
  • Start/stop the container
  • Reinstall, deactivated and activated ONLYOFFICE
