Hello colleagues,
we have a consolidated topology deployment of OCS ENT Edition with one Edge server.
The messaging (Communicator) works fine, all server validations (front-end and edge) are correct.
However, I (a domain user with schema and enterprise admin permissions) cannot connect to the Live Meeting (using Meet now). User authentication succeeds, but after clicking Meet now and waiting a couple of seconds, I get Cannot connect to the live meeting now, ...try again later...contact the support or admin... you know that message 
I am connecting to it using the FQDN of the enterprise pool and TLS as I don't have configured TCP connection. I am able to connect to it directly from the OCS server using poolname.domain.com and from an external PC using sip.domain.com:443, but not from inside the network :-/
Any help would be very appreciated.
Best regards
Ravie
