the unhandled exception originally thrown from this function public async Task<Tuple<MySqlStream, Stream>> StartSSLAsync(Stream baseStream, Encoding encoding, string connectionString, CancellationToken cancellationToken, bool execAsync) at this block of code using (cancellationToken.Register(() => throw new AggregateException($"Authentication to host '{_settings.Server}' failed.", new IOException()))) sslStream.AuthenticateAsClientAsync(_settings.Server, certs, tlsProtocol, false).GetAwaiter().GetResult(); the exception is not handled by the library and cause application to crush

I used "Net limiter" to limit my application internet speed to 1KB In and Out

my steps to hit the bug 1 - create a simple .net application on client machine to connect to mysql remote server using ssl connection 2 - install Net limiter on client machine and give the simple application limit to 5 kb or less 3 - try to connect then the application will crash with no exception catch even if the connection code inside "Try Catch" statement
