I am trying to update my server from 1.21.3 to 1.21.4 and when i do it seems to be working just fine but my friend using optifine or the base minecraft launcher cannot connect or connect for a flash then get disconected. I tried making another server and transferring the world afterward but the bug persist. Using a the new version and the world generated with it work but we want the new version !!!! Hope someone can help me and my friends!! 😁

The game message is the same every time "connection lost    Network protocol error"
