Error while try to connect home server

[Dimness]

My friend and I opened home server and have set everything right, according to the videos and everything.
And there is an error while connecting.
Can anyone solve this?
Thank you.

Hello

I think it's du to the car of your neighbor ...

Seriously, without any informations we can do nothing for you.
Where is the server ?
Can you connect in local ?
What error message do you get ?
Do you check the server log ?
