Minecraft Hamachi Server joins not working?

We're 4 people, one of us has a Hamachi server, we have Hamachi and 2 plus host can join, 4. Not even though the server is open for 5 people. We have tried everything we have thought of, release ports, allow Hamachi in the firewall, various settings on the server, etc. He is the server also displayed as if it did not exist, although he enters the same IP as the rest. We had tried to create a server over it (without Hamachi). In the end we managed to do it, but only he plus another joinen, the other two joins, have a long loading screen and then fly down (at first the people on the server see the message they are out, join them themselves and can't do anything except run around and then fly out). We just have no idea what it is. I ask for help…

Is your internet good enough? If the 2 anyway raushiegen?

I never got Hamachi up and running either. Rent a server

If you want to use Hamachi, you do not need to configure a firewall, because Hamachi creates a VPN…

Leave Hamachi away and release the port instead…

All must also have an IPv4 connection…

By the way, only the one who runs the server (= the host) has to release port 25565 in his router…

All those who only join, do not need to change anything on their routers…

The host must also note that any Internet Security Software is configured correctly.

Then the host has to pass on its external IP, which ER can read on http://www.wieistmeineip.de. He himself joint with 127.0.0.1 or localhost… Assuming he plays on the machine where the server is running…

Incidentally, an IPv4 address MUST be present, with an IPv6 server hosting for the host is out of the question…

By the way, the host's computer has to be on, so that the server can be online, too, and no server is running on a switched-off computer…

If you need more specialized help, I can set that up for you via Teamviewer. Even for free, but only in the evening…

What speaks against port release?

If it is not possible I recommend https://ngrok.com. Download, sign in with the token and then enter "ngrok tcp 25565".
