Kick cause code: group=3 'BATTLEYE', reason=1 'CLIENT_NOT_RESPONDING'

Before 3-4 weeks ago, I did NOT EVER get this error when joining a server. DarkGru has 10 servers, 5 of which are Conflict. I cannot join any of these 5 conflict servers. This issue would occur with usually one or two servers which I didn't play anyway so this error wasn't a big deal to me initially up until like 2 days ago.

I don't even know what changed on my end or the server's end that I play on, because I combed through my computer for conflicting antivirus and network monitoring software, I uninstalled and reinstalled Battleye multiple times and have done multiple computer restarts, I changed my internet, and tried playing on another network, and it still didn't work. I actually tried 4 (!!!) different networks, and I still get this error. I cannot join any of the DarkGru servers, not even the PvE ones, I don't get this issue with vanilla, but I am not seeking to play vanilla. ANY help would be amazing. I've been ripping my hair out trying to fix this error code and cannot find any solutions on the internet.
