Thanks for your report!

Make sure you run kodebrikkesjekken as you are about to use your code device. For SR-bank that means on step 2 as you are asked to enter your one time code.

If you want to use it with BankID on mobile you need to follow the guide on https://www.kodebrikke.no/userguide.html which states that you need to start with ordinary BankID and then choose "Velg annen BankID"/"Choose other BankID" and then choose BankID on mobile before you run kodebrikkesjekken.

Kodebrikkesjekken is not affected by the use of VPN. I run with multiple VPNs myself.
