Unable to callback my application URL after sign in

[Bulb2]

Hello,

I am trying to callback my application URL after authentication/sign-in in Schoology,

here is my authorization URL- 

https://www.schoology.com/oauth/authorize?
oauth_token=*****31031b4a76ebed5edf7eea07b0******&
return_url=dev.bulbapp.com%2Fb%2Frest%2Fauth%2Fauthenticate

It's not able to callback/redirect to my application,

Please let me know that what I have done wrong here or is there anything which I am missing out?

Thanks

Correct return URL is here -  return_url = https://dev.bulbapp.com:9011/b/rest/auth/authenticate

Please suggest me the resolution.
