Hi Yogesh Nahar
Did you fixed you issue? I have a similar problem in this week and I all ready fixed, in my case I needed to enable the OAuth service and check the ecact location of the oauth2callback file on my system, according the documentation and installation you can find on your server over the following path where the moodle platform was installed.
| In my case moodle is installed on / path |
|---|
| marcos@desarrollo:/moodle33/admin$ ls |grep *oauth* oauth2callback.php |
Othe issue was the name... I was typing wrong the name
Right now is working with Google and Facebook, I am working to enable Github.
