Need help with sideloading an app on my iPad Pro

I am trying to sideload an app on my iPad but I keep getting an error that says Internet connection is required to check the files because this is from an untrusted developer

I went to the profiles area and trusted the developer, but when I go back to the app, I still see the same error. Has anyone else experienced this? If so, how did you fix it?

The certificate might be blacklisted. You could use another certificate or back up to iCloud and reset the iPad.

What sideloading app are you using?

I am using Flekstore and eSign.

@Parker
It will still show this error, but in the background, it is blacklisted, so make sure you use a DNS like https://github.com/khoindvnDNS/iOS/raw/main/DNS/khoindns.mobileconfig

Or you can create your own DNS

Your other option is to back up to iCloud and reset your iPad.

Would I need to do a full restore on the iPad first?

Yes, in iCloud

I restored and downloaded some IPAs, and I think I figured it out. When I load my own IPA (eSigner), it breaks the certificate and blacklists me. Not sure why that happens, so for now, I guess I’ll have to do without it.

Well, I managed to download one app. I opened it, and it worked fine. But then I tried to sideload eSign through Flekstore, and that’s when the error came back. None of the apps want to open again. I am really confused right now.

Thanks, this really helped. I can now sideload apps through Flekstore, and I will try my own IPA next. I think it will work. Thanks again.

@Parker
Also, use this link for eSign but don’t get the signed version: https://khoindvn.io.vn

Yeah, that’s the same link I found last night, and it worked great. I didn’t know that certain certificates could blacklist specific IPs, but now I understand.

Would iTunes work just as well?

@Parker
Any signing should work.

@Taylor
Okay, I will try this. I will install the DNS profile first before anything else.

I suggest making your own free DNS with NextDNS so you can update your phone with sideloaded apps.
