Error with any game: Unknown NCA magic (decryption failed?)

[rpaggi]

Hello everyone!
I was testing the Ownfoil and I’ve downloaded two NSZ games and tried to download them via Tinfoil, but when they finishes the download that error appears.
Maybe I need to make some additional config

Idk for sure but I think that's an issue with your switch or your files rather than ownfoil. Ownfoil just serves the files, decrypting them is done on the switch in tinfoil.

Check whether you have up to date keys on your switch and of course check your firmware is up to date enough to install those particular files - firmware 20 is needed for newer games.

One detail I forgot to mention is that if I install the same game via USB, it installs normally, which is why I thought it was a configuration issue.
I even updated my Tinfoil thinking it might be a problem with the application itself.

Dunno then. Try flipping different settings, see if anything helps. Personally I set encrypt shop true, public shop true, dunno if that makes a difference to your issue or not, worth a flip and a try tho.

I will close this as there is no evidence that the issue is coming from Ownfoil, please reopen if needed.
