I bought a membership, but I'm still banned, just because my VPN has the function of automatically choosing the best network!

Today, my network is not very good, and I often disconnect when playing games, so I turned on my VPN, but the VPN seems to be unstable, and I often disconnect and reconnect. My VPN will automatically choose the best route to connect when disconnected. Maybe I reconnected to different IP segments several times, and then my account was marked as a suspicious account, and then was banned an hour later, I am very puzzled about this, is it possible that different IP connections will cause the discord account to be banned? ? I didn't do anything illegal, I was playing the game all the time, and then suddenly the discord was logged out, and I couldn't log in.
