TlsException

Question

The code did originally run with no errors. When the server was relocated to a new subnet network, we now receive errors. The server name can be resolved to an IP address at a command line.

Any suggestions of what is causing this problem?

Thank you!

Answer 1

This indicates a failure to validate the server's certificate (which implies the connection was actually successful).

Unfortunately, this particular issue indicates "other error", and we need to gather additional information to be able to tell what is going on.

But first, could you please lete us know which version of Rebex Secure Mail you use? We have enhanced reporting of these errors a bit recently.
