DTLS Handshake failed

[iLikeCSharp]

Getting an error saying DTLS Handshake failed unsure what the actual error is because it doesn't really say. When it breaks it just says Org.BouncyCastle.Crypto.Tls.TlsFatalAlert: internal_error(80) at line 58

Looking into it a little more, not 100% sure but I'm assuming this might be the problem.

Adding to the last comment, at SIPSorcery.Net.DtlsUtils.LoadSignerCredentials there is a check for supportedSignatureAlgorithms to see if it contains SignatureAlgorithm.rsa(1) but supportedSignatureAlgorithms only contains SignatureAlgorithm.dsa (2) and SignatureAlgorithm.ecdsa (3) causing it to return null which results in a EmptyChain

Should be fixed by #1201.
