We have to expose our Team Foundation Server to the customers over the internet. One customer is able to log on using the WebAcecss (http://MyDomain:8080/tfs) but when he fires up TeamFoundationServer 2010 to connect to server from there, it simply doesn’t work and he got the message: ‘The underlying connection was closed: The connection was closed unexpectedly’.
Do you know the answer to this issue?

It seems like an firewall issue. It works when the traffic is routed through Fiddler. (I accidentally discover it when using Fiddler to find out what’s going on).
These are 2 interesting articles for troubleshooting this kind of issues that I came across:
