@jgb-solutions You should be able to allocate a shared IP address now. We’re working on the billing issue independently to refund these charges.
For transparency’s sake, here’swhy you ran into this problem:
Before, Fly.io allowed free tier users to deploy apps without adding a credit card. This led to widespread abuse of the platform by bad folks, so we now require credit cards for a larger subset of users. Your account got marked as past-due by our billing system.
