SSL Certificate - Could we use a wildcard certificate

Question

We are updating our public SSL certificate and would like to utilize a wildcard certificate instead. Does the application support that?
At the moment - we are getting a error, but we can see that it is using the new wildcard certificate.

Comments

dbFront should not care as long as the certificate allows the browser to complete a valid SSL connection to the web server.   dbFront only reports and warns about the lack of an SSL secured connection.   What error are you getting?

The error we get with with our expired dbfront.domain.com certificate and new *.domain.com certificate is the same.

Error is "the connection is invalid. SSL certificate expired" however, the details below (on the same error page) shows certificate CN *.domain.com with certificate validity until July 19, 2023

Is there a load balancer in the mix?  Internally dbFront uses the Request.IsSecureConnection() call in c#.    See: https://stackoverflow.com/questions/12725859

The issue with using a LoadBalancer is that they are often the termination point for the SSL connection. The LoadBalancer forwards the conversation to the WebServer/dbFront as plain, unsecure HTTP.  This means that the client sees that the connection is running over SSL but dbFront and the WebServer only see HTTP which is unsecure.

One solution would be to configure dbFront to look for custom HTTP headers added by the LoadBalancer.  This would need to be site specific.
