Issue/Introduction

I can open correctly a url with any browser from the same machine where url_response is deployed and see the url after accepting the website's security certificate 

(There is a problem with this website's security certificate > Continue to this website )

 

However, when testing the same url in the url_response probe I get the following error:

Result: 400 The request could not be processed by the server due to invalid syntax

 

url_response log:

Aug 19 14:58:25:637 [8260] url_response: [Profile on 5250] http.Get() returned 400 (The request could not be processed by the server due to invalid syntax.)
Aug 19 14:58:26:141 [8260] url_response: [Profile on 5250] Alarm on error: The request could not be processed by the server due to invalid syntax. (400)

Environment

Release : 9.2.0

Component : UIM - URL_RESPONSE 4.*
