- "Block Online Updates" and/or "Block Game Updates" in Priiloader
- Disable that, backup your NAND after
- Import it into Dolphin and use the update console (verify integrity of NAND first)
- Now it should work properly
(In my case I registered the console into Wiimmfi first, but this error has to do with not being able to connect to the internet as seen here)
Reshade maybe conflicts or disables internet connection when Depth Buffer is available?
