Issue with Environment Variables after Binding Custom Domain on Fly.io

I deployed my client application using the environment variable REACT_APP_STRIPE_CUSTOMER_PORTAL=https://billing.stripe.com/p/login/test_14k9Cw2nYgbz25i7ss wasp deploy fly deploy. Everything worked fine until I bound my own domain. After binding the domain, all the environment variables stopped working and I haven't been able to rebind them. How can I resolve this issue?
