Just in case ANYONE else found this thread and was wondering what combination works. Please read below.
Windows Server 2016
Openfire Focus 0.9.2
Openfire Meetings 0.9.2
If your using LDAP, you MUST create a focus user (IE: firstname.lastname@example.org) and give it a password.
Also, if you’re using chrome to start video chat you have to use the HTTPS link using port 7443 or it will fail.
