[SOLVED ] Cant join dust2 only server

[AARGANN]

I get this disturbing message

Failed to contact game server

whenever I try to join dust2 server, whereas I can easily join DM and funmod servers. This started yesterday in the evening; I knew there were a few players on the server but couldn't join. Do you have a solution to this issue?
Thank you in advance.
