The issue you are facing:
Recently wanted Collabora Online integration in my nextcloud instance, thus I installed a Collabora online VM (which is working just fine).
Since my Nextcloud instance is running of Apache through http & then https is handled by a Nginx reverse proxy setup, I did the same, made sure the Collabora domain internally pointed to the Nginx reverse proxy, and then set the URL in Nextcloud’s Collabora online plugin.
i was then granted with the following message :
Saved with error: Collabora Online should use the same protocol as the server installation.
Though both of them are exposed through https… But well ignored it since some other posts said it should still work… But as you probably guessed, it doesn’t.
Opening any document results in a white page. Is that because something in my reverse proxy setup is wrong? Maybe Nextcloud should be accessed using https directly?
Is this the first time you’ve seen this error? (Y/N): N
