Error: Refused to Connect in Web Console

Symptoms​

Refer to the following symptoms present in your Netwrix Access Analyzer environment:

  • When you attempt to access reports via Web Reports, the following error appears:
Refused to connect
  • The %sainstalldir%SADatabase\Logs\Web\Service.log file in Netwrix Access Analyzer contains the following entry:
%time_stamp% ERROR - Inner Exception
%time_stamp% ERROR - System.Net.HttpListenerException (0x80004005): Failed to listen on prefix 'https://+:8082/' 
because it conflicts with an existing registration on the machine.

NOTE: The prefix may differ in your environment. Alter the prefix as necessary in the following instruction steps.

Cause​

An existing application on the Netwrix Access Analyzer host is actively listening on the affected port. Web Reports cannot be bound to the same port.

Resolution​

NOTE: If the BindingURL node does not contain a port, refer to the default values of 80 and 443 for HTTP and HTTPS correspondingly.

Unbind the port from the application. Refer to the following steps:

  1. Verify the Web Reports port—review the BindingURL node contents in the following document:

    %sainstalldir%Web\WebServer.exe.config

    The BindingURL includes the port number and the protocol (HTTP or HTTPS).

    Config file

  2. On your Netwrix Access Analyzer host, run the following line in an elevated Command Prompt instance to retrieve all reserved URLs:

    netsh http show urlacl

  3. Review the list to find the affected port. Run the following line to unbind the reserved URL:

    netsh http delete urlacl url="%Reserved_URL_value%"

    The output should read URL reservation successfully deleted.

  4. Run the following line to verify that the affected port has a bound SSL certificate:

    netsh http show sslcert

    If the output does not include the affected port, refer to the following article to learn more about the SSL binding: https://docs.netwrix.com/docs/auditor/10_8
