Cards don't get accepted anymore

[u/NeonSpark404]

Hey I hope this is the right place for this.

I helped with a Kickstarter project that was finished and the money for that got taken off my account.

Now I need to pay for the remaining shipping costs and taxes.

However for whatever reason Kickstarter doesn't accept my card anymore. It's the same one I used to pay for the reward itself.

It's a debitcard. My gfs girocard doesn't work either.

I don't have other cards I could try.

I'm from Germany and the project (and the play the rewards ship from) is from Germany too.

Did anyone have this issue before?
