Minecraft Lan World does not work, what to do?

My brother and I want to play Mc Mc in a LanWelt. We're in the same network, sitting next to each other and he can't enter my world. That is always the case: connection timed out no further information

Can someone please help us and tell us what we should do. Is it possibly at the Firewall?

First of all, I assume that you have the same version, that one of you has launched a Lan world (so it has opened for Lan) and the other has the server also automatically displayed in multiplayer (I'm sorry, I'll do that only in detail)

If something has not been like that before, please do so. If you've done everything this far… Was there any error messages or info from your firewall / internet security program in the background?

Which Minecraft version is it?

We wanted to play 1.13.2. And we have both used the same, but then always comes trz the above already mentioned error message. What needs to be set in the firewall to give him or her access to the world of lan?

Hard to say… That depends entirely on the program… My current had never been a problem. But my last did not let Minecraft through at all…

Which program do you use?

What do you mean by program?

To

Well, what security program you used. So what "firewall" it is… There are indeed some programs… From Avira to Kaspersky or BitDefender
