I do have two nextcloud instance and one collabora on one server
ie. 192.168.x.100
- nextcloud1.domain.com using collabora on…
- collabora.domain.com - native, no docker.
- nextcloud2.domain.com using only office
I have nginx on another machine. ie. 192.168.x.10
listening on 443 to send of both subdomains to ie. 192.168.x.100
The incoming router is port forwarding port 443 to the IP of nginx ie. 192.168.x.10
the Nextcloud with OnlyOffice is working (but slow as ever before)
therefore I prefer collabora. But the collabora doesn’t fire any document. Everything loads but for the document which according to the debugger in my browser probably is somethink like:
wss://collabora.domain.com/lool/https%3A%2F%2Fnextcloud.domain.com%2Findex.php%2Fapps%2Frichdocuments%2Fwopi%2Ffiles%2F1740_oc8xxxxxxxx%3Faccess_token%3xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx%26access_token_ttl%3D0/ws?WOPISrc=https%3A%2F%2Fnextcloud.domain.com%2Findex.php%2Fapps%2Frichdocuments%2Fwopi%2Ffiles%2F1740_oc8xxxxxxxx&compat=/ws
the type is “websocket”
it returns this message: Error during WebSocket handshake: Unexpected response code: 500
I am still digging but maybe you can dig along
