Can't connect to TFS 2010

I've tried:

1. Stop Collection / Start Collection
2. Detach / Attach Collection
3. IIS Stop, Strat , Reset
4. Flush DNS
5. Reinstalled TFS

and nothing worked.

I've checked the port 8080 in windows firewall, and was allowed through the firewall but the rule was set to PUBLIC and the network is PRIVATE. Added "private" to the rule and everything works again.
