Verify HTTPS setup before customer deployment
“Before we migrate our customer to a new domain, can you verify that the SSL certificate on their new domain is properly configured and currently valid?”
Diagnose HTTPS errors for support tickets
“One of our users is getting certificate warnings when they try to access their site. Can you pull up the SSL certificate details for their domain and tell me what the issue might be?”
