In most cases, synchronising your Google Authenticator application will solve this problem.
If you are on Android
Please go to your Google Authenticator application and then to your settings on the top right of your screen.
Please click on 'Time correction for codes', then 'Synchronize'. Then try again to enter your Google Authenticator code on Paymium.
If you are on iOS
Please go to your phone settings, select 'General' and then 'Date and Time'. In this section, please click on 'set automatically'.
If it is already selected, deactivate it and then reactivate it. Then please try again to enter your Google Authenticator code on Paymium.
If this does not work, please read this article.
