From the steam login attempt log, It seems that firewall, router, or router firewall does not allow the comms to shard.
There has been issues with some routers in the past that do not like Ryzom small UDP packets at all. They either block them or drop them after timeout (ie 10min disconnect)
@Halon What about the network data? (use wireshark if you dont know what to use on win)
