I am using two servers, each with different domains. One of the servers is a rental server, so it does not allow for detailed settings. From now on, I will refer to the former as Server A and the latter as Server B.
Server A is running and installing NC20 and Collabora with nginx. Server B is LiteSpeed with ownCloud running and installed. I want to use server A’s Collabora with server B’s ownCloud.
When I try to use Collabora from ownCloud in my current state, it warns me that it is an “unauthenticated WOPI host” and I cannot use it.
How can I use Collabora on Server A from Server B?
Server A: Nextcloud 20.0.6, PHP 7.4, Nginx 1.16.1
Server B: ownCloud 10.0.6, PHP 7.3, LiteSpeed
When I write the Nginx reverse proxy as per the official instructions, the error is no longer displayed, but the contents of the file are not displayed.
