Microsoft Skype for Business Server 2015

Hello James.

Thank you very much for the reply and the technet link.

I have changed some configurations on skype topology like the FE's FQDN and the certificate that I was using on the reverse proxy virtual server.

After changing this configuration, the mobile client still can't login, but now I see at the tcpdump that it's reaching the reverse proxy virtual server. That "Can't connect to server" error is not appearing on the mobile client any more, but it keeps trying to connect forever without showing any error.

Looking at the tcpdump filtering on my mobile IP address, I can see some intial communication with the FE server, but after some seconds the virtual server starts to send Resets to the client.

I will analyse this pcap files and try to understand why is this happening.

If you have any clue about it please let me know.

Thank you again.
