Different patch updates

[kenney1996]

Hi, I rent a dedicated server for myself and some friends. I play PS5, 3 friends play on PS4 and one friend uses his PC. Yesterday the ps4 players needed to update their game and use version 1.27 I use 1.26 and the PC player uses the latest version for PC but didn't need to update yesterday. The PS5 player and the PC can join the server but the ps4 players can't. I tried to restart the server and everything like reinstall mods or the game itself but nothing works so far
