Error 102-2156 on Wii U Console.

Hello. I’ve been recently getting 102-2156 on my Wii U. Here’s what I tried:

  • restarting my router, modem and Wii U
  • reinstalling Inkay
  • using a different wifi connection and using a hotspot.

I checked the other topics, but none of them helped. I don’t have a hard drive connected to my Wii U either. I had no issues with this console way back as well (even with Pretendo).
