I started/installed onlyoffice on a webserver my.fqdn.de from current Docker-DocumentServer repo, from docs-install.sh script and by executing docker run -i -t -d -p 11080:80 -p 11443:443 --restart=always -e WOPI_ENABLED=true -e JWT_SECRET=Blablupps -e ONLYOFFICE_EDITOR_LANGUAGE_SETTING=de-DE onlyoffice/documentserver

After that, i can access the Welcome page from onlyoffice by https and start the example.
I go to the example screen and create a file, and when I try to edit i always get the same result:
“The document could not be saved. Please check connection settings or contact your administrator. When you click the Ok button, you will be prompted to download the document.”
After click on “Ok” i get:
“Download failed. Press Ok to close the editor”
Firefox console is full of wss:// errors:

It happens with every install method i tried, so i guess my proxy settings for https-to-http are wrong.
Someone experienced this or can give me a hint?
when i start the docker-compose stack, i get no wss errors in console but same problems “The document could not be saved” → “Download failed”

As for the the provided log and proxy server. Indeed, it seems that the issue might be related to it. Is it possible to disable the proxy server to check out whether it affects the situation?
I tried installation with docker-compose, with the single docker command and with the install.sh script, i always get the same error.
so i guess its firewall/proxy related.
The installation worked before we moved to another server.
Ok, I try to open the port on the server to check, if its proxy related.
