When trying to sign in to Wiimmfi I get error code 61010. When I manage to sign-in, that leads me to 86030 when attempting a connection (join ww, join room, someone joining my open room).

I'm allowed to idle on my friend list, and in my own room as long as it's empty, without disconnecting. I can see my friends added and their activity. I'm loading through the CTGP channel on a WiiU. I've used this connection for MKW in the past without problems. I'm able to play Smash 4 online, on the same console, without issues. I've enabled DMZ, UPnP and set DNS manually as these were suggested to me as general troubleshooters. The situation has been the same for at least a week. I've asked around for the last three days and I'm not getting any closer to a solution

Thanks in advance
