I know this topic is OLD. I've read this topic and many others, but I can't get the answer. Like above, I tried everything. I'm now using Arma Reforger Dedicated Server Tool for Windows by SODA3X. I only want to access this server from inside my network to practice flying helicopters. I have a Server 2019 Box where the Reforger Server is installed with three IP addresses, 192.168.0.100-192.168.0.102. Inside Reforger, I can see my server and it has a 70ish ping. When I go to connect, I am confronted with the Password request. I enter the correct password, then it goes to a screen that says "ARMA" and I wait until I get a connection error (like above). Then I'm stuck.
