Hello,

I had to reset my mac recently and now I'm facing some hard time setting up my env

Hey!

Does this error happen with all other IPAs too? I suspect an issue with this IPA in question.

Every IPA, Esign, and any IPA I download from Decrypted iOS IPA (your tool)

Strange. Could you have another app interfering with Sideloadly perhaps?

Antivirus usually, or a program that's constantly running in the background?

Same things happening to me on Windows 11, Sideloadly has been running fine for years, and now I am getting the exact same error.

All the fixes to iTunes login / adi folder does not change anything. No DNS, no antivirus that could be interfering with Sideloadly, just thought I'd share that it may not be client related.

I'm on MacOS M3, so I doubt it's related to Itunes

Maybe Rook can get a look at this directly in src :D

Ok guys
I found out how to fix this (but not the root cause..)
If you are on Mac and face this bug, please change your network (basically, use your mobile data/another wifi)
