What does cpp 81 Cydia Impactor Error mean?
Here’s what the cpp 81 error displays –
The ‘Network Extensions’ feature is only available to users enrolled in Apple Developer Program. Please visit
https://developer.apple.com/programs/ to enroll.
This error actually means that you have not enrolled in the Apple developer program. Once you enroll in Apple’s developer program, this error will get fixed automatically.
However, not everyone wants to purchase a $99 subscription just so they could sign applications using Cydia Impactor.
CPP 81 error is also faced by Cydia Extender users along with Cydia Impactor users. This happens because Cydia Extender is just an on-device version of Cydia Impactor.
So the error codes and the functionality remain exactly the same.
Here’s how to fix it.
How to Fix cpp 81 Error in Cydia Impactor
Method 1 – Revoke Certificates
The best way to fix this problem is by revoking your certificates. Simply follow the steps given below –
Step 1 Open Cydia Impactor.
Step 2 Go to Xcode tab.
Step 3 Select the Revoke Certificates option.
Step 4 Enter your Apple ID and password.
The same method applies to Cydia Extender as well. You simply need to revoke certificates using the in-app options.
This method will most likely fix this issue. If provision.cpp:81 error still persists, try using other methods given below.
Method 2 – Disable 2FA
This error may also occur when you enable 2-Factor Authentication security feature. While it’s a great way to keep your account secure, it can lead to errors with unofficial jailbreak applications such as Cydia Impactor and Cydia Extender.
Try disabling it and sign your desired IPA file again.
Method 3 – Use a new Apple ID
Create a new “temporary” Apple ID and input its credentials when Cydia Impactor prompts you to do so.
While this might look vague, it does work in many situations.
Method 4 – Update Impactor
Use the latest version of Cydia Impactor. You can download it below.
If you are already running the latest version, try using an older version.
