B2Clogin stopped working after our subscription was re-enabled

Our subscription was disabled due to billing. When it was re-enabled, I could access the resources. Our users cannot login with b2c login. The error is a AADB2C90047. It says the server contains script errors and failed to load. No changes where made and the b2c login was working fine until the service interruption.

Thanks for your time :)

    Hi, My problem is fixed. When the subscription was re-enabled. The endpoints associated with the front door policy were disabled. I re-enabled them. The app is working fine now. B2Clogin is working. If someone finds this question things to check are your front door policy and firewall, backend health, and valid certificates.
