I am a beginner.

Facebook login is implemented in laravel6/socialite.

When I access facebook, I get the following error.

Unable to access this site (on browser)
Invalid request (Unsupported SSL request) (Terminal)
Closed without sending a request;it was probably just an unused speculative preconnection

I tried the following site.

FACEBOOK_API_ID = 25985 *
FACEBOOK_API_SECRET = 94a9da *
FACEBOOK_CALLBACKURL = https: //127.0.0.1: 8000/login/facebook/callback

I couldn't find where the mistake was.

I want you to lend someone wisdom.

Thank you.
