Onlyoffice integration issues

My configuration is as follows:
Linux Home Server (Rocky Linux 8.7), php 8.0, httpd-2.4.37-51 and Nextcloud 25.0.3

I just enabled onlyoffice in the admin settings. All other document servers are disabled.
This is not a docker installation.
I have a valid certificate from letsencrypt (wo-lar.com)

I am stuck at the point of setting “ONLYOFFICE Docs address”.
I tried all possible combinations: https://www., https://www./path to /apps/onlyoffice, https://127.0.0.1, <https://Server IP>

Disable certificate verification is ticked, making it hopefully easier
Secret key is left blank too for the same reason.
I get different error messages:

Errors when trying:

  • Error when trying to connect (Client error: GET https://www.wo-lar.com/e_docs/apps/onlyoffice/healthcheck resulted in a 401 Unauthorized response:
    {“message”:“Current user is not logged in”}
    )
  • Error when trying to connect (Client error: GET https://www.wo-lar.com/healthcheck resulted in a 404 Not Found response: 404 Not Found Not Found (truncated…)
    )
  • Error when trying to connect (Bad healthcheck status)

Haven’t found the solution talking to my fiend google neither.
Thanks for pointing me to the right solution.
