Cannot Launch Webmail SSL Expired - except it didn't

Hello, I can access cpanel.mydomain.com just fine and the Auto SSL expires in June 2020. All good. when i go to Email Accounts > Luanch Webmail I get this: Your connection is not private Attackers might be trying to steal your information from cpanel.mydomain.com (for example, passwords, messages, or credit cards). I checked the SSL and it expired Jan 2019. How can cpanel.mydomain.com and cpanel.mydomain.com:2096 have different ssl? Webmail.mydomain.com opens just fine and ssl expires June 2020. Totally confused. thanks /Johnny
