According to some recent experiences and investigations, it seems that some Iranian users have difficulties connecting to some certain IVAN voice servers. The cause may be due to local restrictions or due to international sanctions. Regardless of the cause, we strongly instruct all members wishing to connect as a controller within Iranian airspace, to use either “eu2” or “eu3” voice servers to ensure all pilots can join the TS2 channel without any problem.

To manually connect to the mentioned TS servers, you can use “” or “” URLs respectively.
