I'm running 5.3.0 on linux. Installed an internal nextcloud (the fork of owncloud) server. That server seems to work through its web interface. Tried to sync enpass with that server. Used the url: http://<my internal server>/nextcloud/remote.php/webdav/ with the right username and password. It says it is "connecting" incessantly. I noticed on a different thread reporting similar symptoms that appears to be an SSL problem. But I am not using SSL. How can I diagnose this?
I should add that I can use a webdav client to access the above-referenced URL successfully.
Adding to this post: I created a webdav server using apache2 (not nextcloud). I could sync just fine. Only doesn't work with nextcloud.
