Internal server error after install

[vomus]

Hi! I am trying to test OnlyOffice integration with Redmine. I run both of them in docker containers. Installtion went fine, I deployed a community edition and tried to edit a few documents, so far so good.

Installing a plugin went fine as well. Then I went to configure it and entered a 'http://localhost:8081' (tried 8082 as well) as an address of the document server because I mapped ports from OnlyOffice container like this:

   ports:
      - '8081:80'
      - '8082:8080'
      - '4433:443'

I did this simply because 80 is occupied by Redmine web interface. I also specified a JWT in my docker configuration and entered it as well. I did not enter anything in the advanced server settings section because I do not quite understand their meaning and I could not find any good explanation of those in the docs.

So, when I did all of that I tried to save the settings and got an 'Internal error' at the page top.

Couldn't find anything in Redmine logs as well as nothing appeared on stdout at OnlyOffice docker...

Can anyone explain what I might be doing wrong?

Hello, Could you try using the IP addresses of both Docs and Redmine instead of localhost?
