Hello. I could create listen servers just a few days ago and everything worked smoothly. But just a couple of days later, my friend tries connecting, but only gets a window saying something like 'Sending punch packets' or 'Server could not verify your Blockland ID'. I've tried port forwarding, but it still doesn't work. Any suggestions on how to fix this?
P.S.: If I connect to his server, I get the same message. I can post logs later.
