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

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.

Solution 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

Solution 2:

Ok follow these steps,

1 - Delete TestFlight Web Clip or icon from home screen.

2 - Delete TestFlight Profile

3 - Important (Go to Safari in settings and Clear History and Website Data)

4. Restart your device.

5. Login to https://testflightapp.com/m/login on Mobile Safari.

6. Tap Connect Device.

Hope this worked for you :D

Bye!

Solution 3:

I just had the same issue. The Testflight-App from the AppStore won't install, saying iOS 8 is required (although we have other iPads with iOS 7.x running the app). The "invalid response"-error occured when logging into testflightapp.com on the device and trying to register it as proposed in testflightapp.com's Help section.

I solved this issue by clearing Safari's cookies and data (Settings -> Safari -> Clear Cache) and then restarting the device.

After going to testflightapp.com again, the device was already connected an everything worked. Hope that helps!
