Error 503 . Server Unavailable


Our application suddenly stopped working. It returns “The remote server returned an error: (503) Server Unavailable” when trying to connect to streaming api. This app has been working for a year but it’s two days that we can’t make it work.

I tried to run it on my own computer with same configuration as production and it worked so I decided to move it to another server (same host company) but it return same Error.

I really appreciate if some one can help.
