Multiplayer (LAN) not working after update

I have been playing one shared world for over two months, without a problem. today the game updated and after I open to LAN nobody can access the world, giving the following error:
minecraft lan io.netty.channel.abstractchannel$annotatedconnectexception connection timed out (...)

I can no longer open any world to lan, but I can access other games.

Hey there! I am currently not able to reproduce this bug, everything works fine for me. Could you please provide more detailed information?

What information would you need?
I have already gone through all the "how to fix minecraft lan not working" tutorials and still nothing.

Same here - LAN doesn't work on Latest Release 1.17.

It doesn't work on previously created worlds (before the update) and it doesn't work on a newly created world either (after the update).

I get the same error for both - like the one in the screenshot. 

LAN worked fine on Latest Snapshot 1.17 and it worked fine on Latest Release 1.16.5.

Make sure your client operates on Java 16. You can use this tutorial for additional help with updating Java.

This is most likely a technical support issue. Take a look at your firewall settings, something might block your connection. For further assistance please contact the Community Support.
