SOLVED Facebook SSO: Can't Load URL: The domain of this URL isn't included in the app's domains.

Re: Facebook Social Authentication: Can't Load URL the solution was enabling Embedded Browser OAuth Login in Facebook Login Settings:

Open your app settings at Facebook Developers portal and make sure your app is Live (App Review > Make {app_name} public?) and Facebook Login is Enabled (enabled by default when creating your app - Products > Facebook Login > Client OAuth Login and Web OAuth Login, both should be set to Yes).

IMPORTANT: make sure Pages APIs is also Enabled, turn on Embedded Browser OAuth Login:

• Embedded Browser OAuth Login enabled (Products > Facebook Login > Embedded Browser OAuth Login Yes)

@h7 Thanks, this helped, in my case with no need to make the app public. It's still "In Development", but working.

The settings at Facebook for Developers are like the following:

Settings > Basic

• Display Name: Example Community Login
• App Domains: example.com
• Contact Email: myemail@gmail.com
• Privacy Policy URL: https://example.com/privacy/
• Category: Some category
• Site URL: https://example.com/community/

Facebook Login > Settings

• [yes] Client OAuth Login
• [yes] Web OAuth Login
• [no] Force Web OAuth Reauthentication
• [yes] Use Strict Mode for Redirect URIs
• [yes] Enforce HTTPS
• [no] Embedded Browser OAuth Login
• Valid OAuth Redirect URIs: https://example.com/community/auth/facebook/callback
• [no] Login from Devices

Well, not sure if all this is needed, but after many tests it's working this way.

There is also the interesting video Facebook SSO for NodeBB - YouTube, which is helpful although not complete.
