Error -26547: Authentication required, please use "web_set_user"

Hi,  

Im currently doing web perf testing and encountering the errors below:

Error -26547: Authentication required, please use "web_set_user", e.g. web_set_user("domain\\user", "password", "host:port");

Error -26630: HTTP Status-Code=401 (Unauthorized) for "some website here"

I have tried applying the web_set_user functionality but still getting the same error and warnings.  

Also, I have this warning comment inside my code. Hoping this will help you give me an adivse.

"/*Possible OAUTH authorization was detected. It is recommended to correlate the authorization parameters.*/"

I have checked some related forum posts but haven't found a way to completely solve my issue.
