Not a recent issue but i wanted to share my insight for the administration on this problem.

For those who don't know Warmane uses some service or platform to block you from login into the game if you belong to a certain network. Due to "Botnetwork". It can get fixed if you login on the website, refresh the page and then proceed into the game. If your ip adress changes you should repeat all those steps. If your ip adress changes when you are IN GAME this won't work and you have to actually change it AGAIN.

My situation is: i am from Kazakhstan. Both major ISP's using Dynamic IP range for all users. Getting static IP cost alot of money monthly and have some downsides too. My connection gets refreshed every day at certain hour and new IP adress assigned. Thats the practice across ALL country and those IP ranges are known. They are not Bot networks or being sold to any shady third party companies, those are just users. That problem didnt exist during Frostmourne season 1-2.

Although i understand why security services might consider those IP ranges bad (due to possibilities of harmful action from some users) for Warmane this is not usefull and do not make any sense. It is just a major hassle for some players every day. I'd suggest to put some exceptions in those IP rules(as in my case) if not remove them whatsoever.
Best regards, player.
