remember to start your server after resetting, I forgot to
:c try creating a completely new server world just to check if that works? check the port address too, try different ones
continuing from above: if renting private server, make sure you download backups to your client side machines. Backups created on server hosting services will be deleted when server is reset. Use FTP to download backups of world files
workaround/fix - server needs a full reset. For some reason there is either an ID or update number issue which despite updating the server doesn't seem to align. Server owner needs to create backup of world, server.properties, world zip or whole server - anything of importance to you. Then reset entire server or delete server and reload. Then load back in backups of previous world and config files server.properties and whitelists etc. Backup is essential before reset.
same problem on console trying to connect to private bedrock server
unresolved, affecting both java and bedrock
I think this was just patched in the latest 1.17 snapshot
Both dosn't work!
see above comments for work around? what platform is the 6th person connecting via,
