Duplicati.Library.Utility.SslCertificateValidator+InvalidCertificateException: The server certificate had the error RemoteCertificateChainErrors and the hash 6F527A2D5926141F10D07DF3512744306DE4968E
If you trust this certificate, use the commandline option --accept-specified-ssl-hash=6F527A2D5926141F10D07DF3512744306DE4968E to accept the server certificate anyway.
You can also attempt to import the server certificate into your operating systems trust pool.
You may want to import a set of trusted certificates into the Mono certificate store.
Use the command:
cert-sync /etc/ssl/certs/ca-certificates.crt #for Debian based systems
cert-sync /etc/pki/tls/certs/ca-bundle.crt #for RedHat derivatives
