Hamachi server for Minecraft - connection problem?

I have recently created a Hamachi server and using the files under https://www.minecraft.net/...ad/server/ a Minecraft server.

I myself can when I started Hamachi and connected to the right server and the Minecraft server (double-click on the Java file) was started, with the ip4 address as ServerIP in Minecraft join.

However, no one else, who is also connected to the same Hamachi server and also the same IP address - which I have used - joinen.

Does anyone have an idea why this might be?!

Do not know how it is with Hamachi (I'm not really a fan of), but did you open the ports?

Yes me and the others have opened for all files

You do not have to open files… Oh my god…

You have to open ports.

I meant the filter.

What kind of filter? Leave Hamachi, it just makes things more complicated.

If you've already released the ports, what else would Hamachi need for that?
