Unable to connect to a repository at URL

[PhilJollans]

I have received this report by Email on 13-October-2020

SharpSvn.SvnRepositoryIOException: Unable to connect to a repository at URL 'https://url_with_self_signed_cert_and_client_cert_for_auth' ---> SharpSvn.SvnSerfException: Error running context: An error occurred during SSL communication
  --- End of inner exception stack trace ---

svn-version=1.12.0
os-version=10.0.18363.0
ankh-version=1.0.0.12
sharpsvn-version=1.12.0.1
command=SolutionUpdateLatest
vs-version=16.0.30523.141

My first impression, is that this should result in message box with the message "Unable to connect to repository" with the URL, and not a crash report.
