Skype Refuses To Connect / Sign In

[dradux]

This is more of a note for other users as I solved the problem.

My docker-skype instance was working fine, after I resumed from a suspend skype would not reconnect. I logged out of skype and tried to log back in and skype would fail with a "could not connect" message. I deleted the container and then the image and it still would not connect.

I then remembered I disabled my local firewall (firehol) for other work. It turns out that I had to restart the docker service after firewall changes were made to get docker-skype to connect again.

Docker makes changes to the firewall tables when new containers are create and so on. Reloading the firewall rules can result in the docker installed rules to go away. I have the following rule added -A POSTROUTING -s 172.17.0.0/24 ! -d 172.17.0.0/24 -j MASQUERADE that resolves the issue for me, where 172.17.0.0/24 is the address space of the docker0 network.
