Hi,
since I upgraded to 2.2.0.0 (on Ubuntu), all of my backups fail with “The SSL connection could not be established”. I use WebDAV to sd2dav.1und1.de which shows “Grade A+” in the SSL Report. Before the upgrade, my previous version (2.1.0.5_stable, I believe) worked without problems.
This is the log:
System.Net.Http.HttpRequestException: The SSL connection could not be established, see inner exception.
---> System.Security.Authentication.AuthenticationException: The remote certificate was rejected by the provided RemoteCertificateValidationCallback.

I have been trying several times yesterday and today – always without success.
Any hints welcome. Feel free to ask for more details.
Kind regards
