"The requested URL was rejected. Please consult with your administrator"

the message somewhat looks like its from ASM [looks like violation and should have a accompanying support id] or APM SWG [forward explicit proxy]. are you using a http proxy?

F5 ASM is likely to be blocking automated requests thinking you are a bot. Make sure your http connector request includes a valid User-Agent header

Hi Boggs,

Thanks for response,I am not using http proxy. This is my support ID : 2727016049356909475

First of all you have to verify of this is error os originating from the f5 i.e. 'irule' or actually from the application, mu guess is this is coming from the application.

If i was you, I'd run a 'snoop' on the application and see what is happening.
