I have made sure the local firewall is not interfering with 443 traffic. If I start the prtg server service using port 80 I am able to get to the start page. However when I choose to use 443 for SSL the service restarts with out issue but the page is not available. Running a netstat on the prtg probe does not show that 443 is a listening port either.

Definitely need SSL as this will be integrated with AD.

So I believe the issue SSL v3 was enabled on the server 2012 instance PRTG was installed on. With an older version of IE support SSLV3 i was able to get to the https page now. However this is not ideal. On the Server 2012 PRTG probe I have disabled SSLV3 and enabled TLS versions via IE on the server however it sill appears to be using sslv3 when excepting the ssl connection from the client.

Should I be disabling SSLV3 somewhere else in server 2012

Silly error on my part. Updating the version of PRTG disabled its use of SSL v3 resolving SSL issues with browsers only supporting TLS.

The latest 15.1 version resolved the issue.
