Failed to restore with error code E_UNKNOWN and a TLS error caused the secure connection to fail

Hi all,

I was hoping someone could help with this. I have an app that requires a subscription To access all content and features. However, some of our users’ subscriptions are not being detected and when they hit “Restore” they are faced with the error:

“Failed to restore with error code E_UNKNOWN and a TLS error caused the secure connection to fail“

We have asked the users to disable VPNs, change networks / data connection, restart devices etc. but this doesn’t seem to work. We are unable to produce this error on our test devices. Nor can we see any obvious issues in the code or on the servers.

Anyone any idea what could be causing this?
