When trying to connect to Foglight via https, the following error appears in the browser:
Your connection is not private.
This server could not prove that it is MyServerName.MyDomain.com; its security certificate is from [missing_subjectAltName]. This may be caused by a misconfiguration or an attacker intercepting your connection.
The used certificate has not set the Subject Alternative Name.
When using a CNAME (alias), the Subject Alternative Name (SAN) needs to be set for both, host name and CNAME.
Please create a certificate where the Subject Alternative Name is set properly.
Once the new certificate is created, import it into Foglight, the steps are here.
