Hello @woohoo
I have compared your compose file with my one, which I used in the past: Installed Onlyoffice using Docker-compose and it's loading indefinetely - #2 by Alexandre
As far as I understand, your file is missing the ‘cgroup: host’ line and the hostname. Could you please run a test and use my sample to check out if the issue still occurs?
Additionally, please try to check it out without proxy server in front of Workspace.
