Facebook login: Can't load URL: The domain of this URL isn't included in the app's domains

[Trung Đức Nguyễn]

I'm setting up Facebook login on my Keycloak deployed on a Kubernetes cluster, followed the latest documentation and keeps getting the error "Can't load URL: The domain of this URL isn't included in the app's domains. To be able to load this URL, add all domains and sub-domains of your app to the App Domains field in your app settings". I have configured the following:

• Settings -> Basic:
  • App Domains: MY_DOMAIN
  • Website: https://MY_DOMAIN/auth/realms/pvcombank/broker/facebook/endpoint​
• Facebook login -> Settings -> Valid OAuth Redirect URIs: https://MY_DOMAIN/auth/realms/pvcombank/broker/facebook/endpoint​

I'm using Keycloak 12.0.1.  MY_DOMAIN  is a local domain resolvable by my company's local DNS, not yet public to the Internet, but I don't think that's the problem since Google login works fine.
