"Device is not registered. Please try again" error

Came back to use the app after a few months and prompted with this message.

Hello ladadragunov

This error usually arises when the app does not recognize the device you’re using. Here’s what you can do:

  1. Log out of the app on your device.
  2. Clear the app’s data and cache from your device settings.
  3. Reinstall the app from your device’s application store.
  4. Once the app is reinstalled, log in again.

This should rectify the issue and re-register your device with the app. If the problem persists, reach out to the app’s support for further assistance.


The app didnt even ask me to login. All i had to do was installing VPN profile. When the app did work in the past, i didnt have to login either. Reinstalling yields the same error but luckily the PC version of the app still works fine.

I do have this same issue… i am trying to use it on an android 6 device.
in diagnostics section of the app
I see in client configuration - ID = not found; public key = not found.
and following ‘N/A’

i did try all your recommended procedures but only thing that is left is to format my device and check.
