Not sure since you did not specify which certificate error you are getting, but my guess is that you may have generated a self-signed certificate that needs to be deployed to your clients as a root certificates via GPO:

Otherwise, make sure that you are entering the name the same way it is in the certificate (server1 and server1.domain.com are not the same thing).
Please mention the error for further assistance

Is there a 'view details' or something to that effect?  See if you can get a little bit more details to make this more efficient, otherwise most certificate validation issues can be resolved from the steps in my article:


If you're still having issues after going through that, please post an update, if possible include a screenshot.  
Cert details should show a Subject Name (SN) and Subject ALternative Name (SANs).

Ideally your cert should look like this:

SN= FQDN of Std Edition Server
SAN2=FQDN of Std Edition Server

Fix that, restart services, then ensure you are using automatic configuration (SRV record in DNS).  If you are manually configuring, you cannot use an IP address, you need to have the std edition FQDN listed. (Cert is name based, not IP based)
