Any kind of unity rippers stopped working since the 2019 version i think (it was a security measure). To make the networking i used Mirror. I won't be making any updates on this since the original game is actually getting a multiplayer update.
Oh, thanks, I used ripper for fun 2-3 times, it never worked fully either way but I am not sure why. Also I didn't know the original game gettting multiplayer, sorry.
