Testflight Profile Installation Failed, the SCEP server return an invalid response

Question

One of my user is having trouble installing the TestFlight App (not Apple's TestFlight).

He encountered the error: "Profile Installation Failed, the SCEP server return an invalid response."

I advise him to follow the steps listed here: http://help.testflightapp.com/customer/portal/articles/402816-registration-issues

He told me that he has no profile installed in his profiles and after following the steps, he still encounter the same error.

I at a lost as to what to do now and any advise will be appreciated.

Answer 1

I finally got my testers to get past this SCEP error. Hopefully this works for you too.

Workaround:

1. Open the iOS Settings app, select Safari then tap on "Clear History and Website Data"
2. Open the Safari app and go to testflightapp.com
3. Log into your TestFlight account
4. On the "Connect this device by installing profile" screen, tap the green button "Connect Device"
5. Tap "Install" on the "Install Profile" screen
6. If you have an unlock passcode on your device, you may be will be prompted to enter it
7. When the SCEP error comes up, tap "OK"
8. Tap "Cancel" on the "Install Profile" screen
9. You should then be redirected to TestFlight in Safari with the "Device successfully connected!" message
