Having a hard time making ZeroTier work

ZeroTier, vpn tool much like Hamachi, but way more stable and generous on the free side of things.

I’m having an issue after installing it through Octopi. The installation went fine, it is detected in the system and while the curl command to install it won’t work on Cachy (or arch for that matter it seems), the command does detect the already installed version.

Problem is, it’s not starting at all. It tries then exits saying It’s “Missing port and zerotier-one.port”. It seems to have also made a new user and two folders on my main user home folder.

I need this for playing Vintage Story online with friends, specially since I’m planning on making a server in January. I posted the issue on the zerotier forum too, but they tend to take a while to answer, so I’m looking for help with the OS community directly.

It could be that the firewall we are using is blocking ZeroTier. Allow the port that ZeroTier uses or disable the firewall.

I did that, the port is 9993 and the firewall is UFW, right? It’s allowed.

I… I checked again today and… it’s connected? Either I needed a restart or it’s a Christmas miracle.
