I have Nextcloud on a Raspberry Pi, and I’m using port 8443 for SSL with a locally signed certificate only. I connect to Nextcloud using SSL without a problem, but iOS CalDAV can’t seem to make it happen.
First error is “can’t use SSL.” I’ve tried Advanced Settings, and tried both enabling SSL, as well as disabling and changing the port to 8080 (though per Nextcloud security I have a force on the server side to use SSL).
