I made an aternos server with 1.17.1 spigot. But there's this weird problem that some friends of mine who are using cracked clients can't join the server with 1.17.1. They need to join with 1.16.5 (the server has viabackwards) but they are missing out on a lot of 1.17.1 features and this ruins the main reason for making a 1.17.1 server. They have also noticed that they can't also join other ATERNOS servers with 1.17.1 but it works with other non-aternos 1.17.1 servers. Why aternos please look into this problem and fix it as soon as possible.
