When you don't ignore TLS customer received this error as of yesterday. Customer always had ignore TLS deselected.

Error occurs with 2.51, 2.6 and 2.7. Previously with ignore TLS option deselected it worked fine.

If you do enable the ignore TLS option and cold start the probe the certificate error disappears from the log but the emailgtw Test still fails and the Test result button turns red as if it failed.

Solution is to REMOVE the username and password from the configuration when ignore TLS option is selected. Then the button turns green. The probe is not ignoring the username and password fields when ignore TLS is selected.
