Can't connect onlyoffice with filerun in docker network

[hamx01]

Hi! I have docker network and onlyoffice container with filerun container in it.
This is OnlyOffice plugin configuration in Filerun:

And this is how I run container of onlyoffice:

The issue is that when I try to open some document with the onlyoffice I have that:

But if I put the onlyoffice behind the reverse proxy like Nginx Proxy Manager it works great. I think this issue is related to headers.

I already tried to reach document server by IP, hostname, port forwarding and nothing worked, only reverse proxy.

I can send more screens and provide more info, if it only necessary
