SMTP Provider setup - cert problem

[adamltl]

I have godaddy cert on my SMTP server running TLS on port 25. When I try to use SMTP Provider I’m getting:
“details”: {
“email_type”: “try_provider_configuration_email”,
“to”: “xxxxxx@xxxxxxxx.com”,
“error”: “unable to verify the first certificate”
},

What is wrong ? mxtoolbox shows my SMTP/ TLS is OK
