Round table

I have a problem here:
I can't start the game - it gets stuck on "getting headers from the host." I've tried using Garena and Hamachi, with players from different countries (with one of them, the ping was quite normal, around 90ms), and on two different versions of the game. What could be the problem?
The firewall is disabled.

The issue is that, often, due to a large number of maps or saves on the server's side, the client cannot handle such a large amount of information (when reading map or save headers).
Delete or move all maps located in the Maps and Random Maps folders, for example, to a subfolder, but leave at least one map in the Maps folder that can be used for online play.
Do the same with the Games folder, where the game saves are stored. Leave no more than 10-15 necessary saves in this folder, and delete or move the rest to another location for storage.
