No one else can connect to my server

[AKANFatality]

I set up a server for BFBC2 through the R34 server files. I can see it in my server browser, I can join it, connected it to ProCon. But there is a problem, no one else can join my server. I get a Player requesting entry post in my log but then nothing happens and they can't join. (Highlighted part of the log attached)

Any help appreciated!

Update: I get a 'TnT/Core/Streams/SocketStreamManagerTcp.cpp(61): "Main": Warning: Only localhost will be able to connect' in the log, is this somehow related to the issue?
Update 2: Some people were able to join, while some couldnt

Okay, make sure your port is open for external users: Run server and check port via this site: http://portchecker.co/ - enter there your IP and server port, if its open - all ok, if not - you need to open it (in router and/or firewall).

I did that, some players were able to connect, while some could not. So I downloaded the latest server files, reopened all ports, and now it works.
