Scanning valid a valid paper QR-Code vaccination Certificate generates "an unexpected error"

The Name, First Names and Date of Birth are correctly extracted from the QR-Code.

This is a lineageOs android without google tools and a simple wifi connection. Using the european checker on f-droid, the certificate is valid.

this is with Version 2.5.0 (2500) (Verifier)

How can I get better logs?

seems the service here is unavailable https://covidcertificate-app.bit.admin.ch/app/delivery/v1/ which is making the app fail.

Version 2.5 changed how the national rules are fetched from the backend. The new backend was not yet deployed to production when you tried v2.5 yesterday. It is/was marked as a pre-release for a reason ;)

Could you try again to see if it works now?

I am experiencing the same issue on a Nokia Device on Android 11 using the F-Droid Version 2.0.0. Is there anything I can do to debug this?

rachyandco commented 3 years ago

works fine on 2500 now! certificate is green when checked

@SamuelNitsche I assume 2.0.0 worked before, but stopped working? In that case it sounds very similar to https://github.com/admin-ch/CovidCertificate-App-Android/issues/206#issuecomment-902556960. Then clearing the app's data may fix it.

If you want you can use adb logcat or use a logcat app to see if there's anything useful. There may not be anything though - so far we are rather conservative when it comes to logging, since pre-installed apps can read the system log. Additionally, the networking error (G|NWF) isn't very detailed at the moment unfortunately. So you need a debug build (which has more logging) or network interception to see what exactly is going wrong.

I installed the app on three different Android phones and f-droid version 2.0.0 works perfectly fine on two of them. It doesn't work on a nokia phone using Android 11 (latest available version).

I will try to check the logs for something useful.
