Social Network Login Failure


#1

Dear all, I was previously logging on to my DL Studio via my local computer
( http://127.0.0.1:80/app/) and using it without any problems.
However, when I tried to login today , it always displayed this problem (below) and I couldn’t login and use DL Studio on my computer.

Social Network Login Failure
An error occurred while attempting to login via your social network account.

I’m sure I’m writing all my login credentials correctly. Can anyone help me please?
Thanks a lot in advance.
Best regards.
