Kindly change the redirect URL to http://domain.com/FacebookAuthentication/LoginCallback in section Client OAuth Settings of the Facebook.

Thanks!

Thank you for your reply.

I changed url to http://domain.com/FacebookAuthentication/LoginCallback but it doesn't work and gives error: URL Blocked: This redirect failed because the redirect URI is not whitelisted in the app’s Client OAuth Settings. Make sure Client and Web OAuth Login are on and add all your app domains as Valid OAuth Redirect URIs. when I click button "Sign in with Facebook"  

Can you suggest alternative solutions please.

Thank you

            return Challenge(authenticationProperties, FacebookDefaults.AuthenticationScheme);

Could you debug the code? if so then check what RedirectUri is being set while clicking on Sign in with Facebook.

I am using nopCommerce version 4.1 and the default Facebook Login Plugin: Facebook authentication
My website cannot login by facebook account.
After I changed the Valid OAuth Redirect URIs to https://domain.com/FacebookAuthentication/LoginCallback and tried to login, there is an error message in the Facebook login page (Just above the empty UserName). It is

"URL blocked
This redirect failed because the redirect URI is not white-listed in the app's client OAuth settings. Make sure that the client and web OAuth logins are on and add all your app domains as valid OAuth redirect URIs."

If I use the url: https://domain.com/signin-facebook, it has no such error message but still fail to login by Facebook. It will redirect to a page:
We're sorry, an internal error occurred.
Our supporting staff has been notified of this error and will address the issue shortly.
.....

However, at that time, if I go to the Facebook official page, my facebook account had been login.

has anyone found any solutions for this?

Kind regards

"URL Blocked: This redirect failed because the redirect URI is not whitelisted in the app’s Client OAuth Settings. Make sure Client and Web OAuth Login are on and add all your app domains as Valid OAuth Redirect URIs."

if someone have any solution i wolud be grateful
Thank you

Is you site running SSL ? Because you can not use the plugin unless you have a valid certificate installed and I have setting securitysettings.forcesslforallpages = true
If your website is called
    https://whatever.com
then the Valid OAuth Redirect URIs is
    https://whatever.com/signin-facebook
and I also entered
    https://www.whatever.com/signin-facebook

All the other settings I have are:
Client OAuth Login: Yes
Web OAuth Login: Yes
Enforce HTTPS: Yes
Force Web OAuth Reauthentication: No
Embedded Browser OAuth Login: No
Use Strict Mode for Redirect URIs: Yes
