If you for some reason can't see adnotation here is what you need to do:
1. In Steam right-click on Dota 2 game
2. Choose Properties
3. In General Tab click Set Launch Options...
4. In TextField enter:
+clientport 80
try different ports if this one won't work some people suggest to use ports between 27005 and 27032
5. Click Ok
6. Launch DOTA2 from Steam.

So hey guys ! Im writing to this forum as all the forum threads didn't answer my problem . So here it goes , I am unable to join matches more frequently than before and out of lets say 5 games I will be able to join 2-3 of them while the other 2 will have this error "disconnected from server unable to establish connection" I was hoping you guys would help me out . I also opened the console when I was connecting to the match and it would be connecting non-stop till i get dc from it . It is not my ISP nor router as my friend came over a couple days ago and joined a server without any problems what so ever , so I'm relying on you guys for help and possibly answers :)
Hope to hear from you guys soon
