Can't start a meeting

Can't start a meeting

I have been able to start meetings in the past with no issues but since we changed firewalls I can't anymore. I've worked with the firewall admin to verify that nothing should be blocked and we've watched the network traffic.

I can get as far as the toolbar attempting to connect, eventually it goes gray. This has happened on a number of different computers two of which I've used in the past successfully. Which is why I'm thinking it's a network thing.

Do you have any documentation about what needs to be open on the firewall? I've attached my log file if that helps.

Thanks for any help you can provide.
