I have configurations owncloud and collabora together in my machine.
I putted reverse proxy NGINX in front of them.
It was working fine when I did it without SSL,
(nginx → owncloud → collabora)
then I wanted to try to implement SSL termination on my nginx and implement cloudflare tunneling to access it from the internet.
so the configuration becomes this.
(cloudflare → nginx → owncloud, cloudflare → nginx → collabora)
Now each time I open my document in owncloud + collabora, I get this error message
I only able to find these logs in the collabora log file.

this is the only log I got in owncloud when I tried to open the document
{"reqId":"9GhSxxxxxxxxxxxx","level":1,"time":"2025-05-19T00:37:14+00:00","remoteAddr":"24xx:26xx:7c1:13xx:adxx:2da5:xxxx:xxxx","user":"admin","app":"richdocuments","method":"GET","url":"\/apps\/richdocuments\/documents.php\/index?fileId=5&dir=%2FDocuments","message":"Generating WOPI Token for file 5, version 0."}
it seems the Collabora able to connect with owncloud, but maybe there are some issues on the data transmission. maybe my nginx configuration are the problems?
but I’m able to open the admin page on Collabora without an issue.
