You have to delete the key.dat from this computer in Documents/Blockland/key.dat
The IP you're using to auth with the master server is coming from a different country than the one you're using to connect to the game. You appear to be using some kind of proxy or other anonymization service.
Maybe a huge possibility of key being stolen?
Actually now that I look at it, yeah. It's flipping back and forth rapidly. I'm going to flag this account as steam only to lock out the other person. You'll have to run the game through steam.
Thanks Badspot, does it say that I'm using the anonymous service or the other person? 'Cause I use a VPN sometimes so I don't know if that's the cause
I'm getting this exact same problem when I try to join some servers like the badspot speedkarts one.
Are you using a proxy server?
Nope I'm not using one, everything normal, Blockland is firewall trusted, my antivirus is MSE, and works like always with Blockland and my 20 other games.
It can be an issue with your IP. Either that or the server is having issues trying to auth you.
