Resolving the error is quite simple, on the https://github.com/smiley22/S22.Xmpp/blob/master/Core/Sasl/Mechanisms/SaslDigestMd5.cs file, on line 154, we have

string digestUri = "imap/" + fields["realm"];

it should be replaced with

string digestUri = "xmpp/" + fields["realm"];

I can prepare a patch later on

After changing this the issue is solved
