Cant connect to the server

For some reason after updating my minecraft to V1.16.00 (nether update) every time I try to connect to the server it says internal server error I've tried joining multiple times also used different accounts asked some of my friends to join but they all gave the same internal server error page could you please fix this (And the aternos server is on PocketMine-MP 3.14.0 or simply the newest version)
