Collabora Office Docker with Nextcloud (bare metal install) - Document loading failed with office document

[wwe]

I’m running out of ideas if you pass all checks still doesn’t work. the error

@Kimimaru

Failed to establish socket connection or socket connection closed unexpectedly

indicates some connection issue. I have no idea which one but there must be something (wild guessing: multihomed system, changing DNS, firewall killing connections). There was similar issue shortly CODE integrated server - documents not loading the user solved the problem with a hosts record

@akuropka

Searching the net for 400 errors and blank pages brought me to this issue: Opening Documents returns an empty screen and a HTTP 400 error · Issue #115 · CollaboraOnline/richdocumentscode · GitHub . Though the case didn’t apply to mine (the server is directly connected to the internet), adding the domain name to ::1 in the hosts file did fix the issue.

as your server is partly bare metal maybe communication out/into the container is going some strange path?

systematic troubleshooting

I would continue digging into the logs to see where it happens. as you see in edit file using WOPI protocol there is quite a lot communication between the systems

• activate reverse proxy and NC webserver access log, increase the log level of CODE, Nextcloud to debug and reproduce the issue
• track every request from the browser to Nextcloud, to CODE

CODE logging

• Making sure you're not a bot!
