first of all, sorry for my bad english.
Here is my question: I'd like to rent a server with two slots for me and my father but in hell I don't find any host where i can rent a cheap server on version 1.7.1. The only one i found is dawnservers but they have serverversion 1.7.0.
Maybe you can help me to find a host where we can rent a 1.7.1 server?
I'm sorry I'm a bad English speaker too.
You mean you want to host an ottd server by yourself?
There is no rental ottd server anywhere.
You have to get a server machine and install ottd, or you can join the public server.
If you want to host a server, I recommend you to try Ubuntu server.
