Hi there, the wildcard domain of dont have a SSL if you look at this crt.sh | jbgmortgage.wpmu.mortgagejv.com. Any thoughts on how to fix this issue? I ran autossl but seems it doesn't work.
First, I am not expert at cPanel. But, maybe this info helps you understand the problem better
I see the cert for your wpmu.mortgagejv.com domain issued Oct18. And, I see you are using a self-signed wildcard cert for the jpgmortgage subdomain of that. As you note, this self-signed cert is not valid for general public internet use.
To get a wildcard cert from Let's Encrypt you must use the DNS Challenge. For your Oct18 cert you may have used the HTTP Challenge instead since that was not a wildcard cert.
I can't tell if cPanel error is because you already created a self-signed cert. Or, maybe is failing the DNS Challenge. Read about challenges here.
While you wait for a volunteer here with more cPanel expertise you might try a cPanel support forum. Or, don't request a wildcard cert for your jpgmortgage subdomain and see if that works.
