Minecraft Lan Welt not working (internet amplifier?)?

Me and my brother want to play together on a Lan world in Minecraft. Unfortunately, we both have the mistake that we can't see each other's Lan worlds. Can it be because we both use an internet amplifier? However, we both use the same internet amplifier. We have tried a lot, e.g. We tried different settings in the firewall and tried to connect via the IPv4 address and the Lan port. Unfortunately, in our case it is not possible to establish a direct connection with a LAN cable. I don't know how to solve this problem, it would be very nice if you write me solutions. I thank you in advance. Stay healthy!

I had this too. It stopped working on a certain version. If it just doesn't work, you could also set up an Aternosserver and play there.
