http 407 status error with SQL stored proc

Hello!

I am trying to complete a HTTP post request via a stored proc.

The query returns the error: sp_OAMethod http status  407 which leads me to think proxy issues and that the request is never making it to the server.  The prints are in there for troubleshooting and it seems to break after step 5.

Any help would be greatly appreciated


Thanks!
