How can you play SkyFactory 4 for two?

I would like to play Sky Factory 4 with a friend, but I can't start the server I downloaded from Twitch and the Install.bat doesn't work either, so I wanted to ask if I could also make a server (please free of charge own both Hamachi)

Create a server on http://Aternos.org.

It's completely free. However, the server stays online only as long as you play on it.

Choose Skyfactory 4 as the server software, which can be found under Modpacks / Curse.

OK thanks

Thanks worked

I'm happy, no problem, wish you a lot of fun.
