2966710 - ERR_CONNECTION_REFUSED

Symptom

When executing a URL, the following error message appears (exactly in Google Chrome, in other browsers the structure can be different):

This site can't be reached
xyz.com refused to connect
ERR_CONNECTION_REFUSED


To get more evidence of this issue, it is necessary to take an HTTPWatch trace while the problem is being reproduced (see in KBA 1558903 - How To Trace a Portal Scenario Using HttpWatch).
If the following result appears in the generated file:
Result: net::ERR_CONNECTION_REFUSED

  • It indicates that no existing connection to the server was available for use by this request and the browser is creating a new TCP connection to the specified IP address.
  • The request returned a HTTP status code failure or caused an internal browser error. Failing requests may prevent a web page functioning correctly and cause performance problems.
  • No response headers received because request failed: net::ERR_CONNECTION_REFUSED.
