I use a Mastercard. At first, I tried to subscribe to the Hobby plan, and my card was successfully verified — my bank balance even decreased by 1 dollar for verification.

However, as you can see in the image, an error appeared. I then clicked the “Pay Invoice” button, which redirected me to another page showing a bill of US$0.51 with invoice number #RPOXHCJY-0002.

But when I tried to pay, my card was instantly declined, even though it had already been verified before.

I also received an email from Stripe (Railway Corporation) saying this:

"$0.51 payment to Railway Corporation was unsuccessful

We attempted to charge your Mastercard ending in (my 4-digit card number) for your Railway Corporation subscription again, but were unsuccessful. Please update your billing information to continue your subscription."

However, my card should be working properly — I’m also subscribed to Windsurf pro using the same card, and that subscription works perfectly fine.

Could you please help me resolve this issue?

Thank you for your attention and assistance.
