Hello,

I'm trying to configure the mail server in the Nintex RPA Console, but I'm unable to complete the configuration.

When I click Test Notifications, the test fails and the following error is displayed

Could you please help me identify the cause of this issue and advise how to resolve it?

I have attached a screenshot of the error.

Thank you.

Check the SMTP certificate

From the Console server, run:

openssl s_client -connect <smtp-server>:465 -showcerts

 

Verify:

Certificate is not expired.

Hostname matches the SMTP server.

Full certificate chain is returned.
