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).
