Like UnrealTai said, its a netcode issue - exists already since way back (in ARR), usually happens only on frontline maps. Don't bother about it, everyone gets it, sometimes almost 3 groups get kicked at once.
Could have become worse because there are more positional gapcloser/backflip skills since 5.0 than ever - they usually behave bad and make you dc slightly more often.
There are free VPN available that usually fix issues like lagspikes and freezes enough to be playable for a MMO. They sometimes have tunneling/routing issues on the provider side.
Try protonvpn or google. If you don't have noticeable lags/freezes in game, I wouldn't bother, it's still netcode issue on their end.
