I have installed OwnCloud at a Raspberry Pi where I use the calendar app. I have access to this OwnCloud from the internet. I have a second Raspberry where OwnCloud is installed, too. This installation is only for internal use but the calendar app is also installed. Both are in the same network.
I have one calendar that I like to synchronise on both OwnClouds. At the moment this calendar is only at the Raspberry that I can reach from the internet. At the second Raspberry I clicked on "New subscription" and used the Link that I copied from the calendar at the first Raspberry. But I get an error:
Error requesting resource on remote server. This could possible be related to a certificate mismatch
Any ideas what's wrong??
