I'm pretty sure i don't, turned off firewall etc just to be sure.   Must just be my phone or something, nothing ever works nice and simple for me lol. I'll try on my other PC when i get a chance to see if it's something to do with that.

Do get back to us after testing on the new PC. I have sideloaded unc0ver on 13.2.3 and 13.5 without an issue.

Which options do you enable in Sideloadly advance settings?

Firstly i had nothing selected and got that error code, then I tried "Try to support iOS 8+"  just to see if that changed anything and got the same, then I read on another thread turning on "Do not use Anisette Authentication" and creating an app specific password fixed someone else's issue, but then i got the Xcode 7.3 on that attempt.

Exact same issue here :/ I managed to install it once fine, then used ReProvision to sign the app (which doesn't seem to work anymore) so maybe we need to revoke all certificates? (i think that's what it's called?)

hello, i recently encountered the same issue as well on my iPhone 11 Pro Max iOS 13.2.2, but i managed to find a solution after trying nearly everything out, so, i backed up my iPhone using iTunes, then i decided to factory reset my iPhone, tried altstore and sideloadly out, they both work perfectly fine now. you could also retrieve your backup and it will be fixed, you just have to reinstall altstore or sideloadly again.
