I have two nextclouds, one with IP address of 192.168.67.200 and one with IP address of 192.168.67.198. They are all configured with SSL and can be accessed through HTTPS. And the two servers can be pinged,
However, when I share a file on 192.168.67.198 to a user on 192.168.67.200, I fill in the sharing box with the user’s federated cloud ID: email@example.com , indicating that the creation of the share failed and the server could not be found.
I checked the log. Here is a screenshot of the log.
