"Error performing query" during gift card activation

I have bought a gift card and while trying to redeem it I have run into problem of getting "Error performing query" every time I try to activate it. It's a US card, so I'm using a VPN to activate it, but it still doesn't work. I have reinstalled Meta Horizon app several times and tried several VPNs but still get this issue. Is there any other way to resolve this issue?
