I am using stackoverflow javascript authentication api. I am getting the below mentioned error.

Application Login Failure
An error occurred while login into an application.

Error Details

error description: could not parse proxy url

I checked regarding this issue and i found few urls.

Bug in the StackExchange Api ? getting "could not parse proxy url" when user not logged in

Resurfacing bug: "could not parse proxy url" error message

Still i couldnot solve this. Any help would be appreciated.

Is there any other way apart from Javascript Authentication to get an user's stackoverflow reputation?

Please do help me on this.
