Input lag that forces the server to kick me

I'm pinging the realm's domain and I got ~40 ms, at its worst, nonetheless the server in the game is freezing - I can move, but everything around in the game is frozen and I can't interact with it until it eventually unfreezes EVENTUALLY before the server kicks me. If it was minor lags and freezes, I wouldn't bother complain, but those are holding the game still for me until I'm kicked most of the time. I scanned the subdomains of the server and I have almost perfect connection to everything, yet, I lag hard af, man.
