I have a problem with the server MC Central/Minecraft Central, which has the ip mc-central.net. I've loved this server for a long time, but unfortunately, after a little break from Minecraft, and on a new computer, I fail to get on the server.
Every single attempt, I can get on for a few seconds before MC Central kicks me and displays the message 'You seem to be using a VPN or Proxy' (as shown in the screenshot uploaded), even though I know I clearly am not. I've tried this several times with 1.8.9, 1.9.4, and 1.12.1, but none of them work. I've even tried this with different wifi. Nothing seems to work.
Something really important to know is that I use VPN sometimes as I live in China, and many websites such as Youtube need VPN to access. I do not use it often, and it slows down my internet speed, so when I play Minecraft, I NEVER turn it on. I don't know why the message shows up, and why I get kicked.
Also, the same thing happens to me when I try to get on the server called Jumpcraft, which is a parkour server with the ip play.jumpcraft.org. They may have the same plugin.
EDIT: A similar thing also occurs when I try logging into Happy Hungergames, ip mc.happy-hg.com
