Server connection issue (Tropico 5)

4 days ago I bought the game, I wanted to play online with a friend. His connection is stable, when I connect, I get a count of up to 100 and an error occurs. Error connecting to server error 11002 . The most interesting thing is that everything is fine in the firewall, there is no blocking, and I entered the cooperative a couple of times. But it happens like this, the game does not work on, you can restart it, and maybe only 10 times. What's the magic? Help
