Error that the site cannot be reached when Qlik Sense is trying to authenticate the user
 
The following error is in the system proxy log:

domain\user SSL authentication server was not started on port 4244. Port most likely bound by another process 
Failed to listen on prefix 'https://+:4244/windows_authentication/' because it conflicts with an existing registration on the machine.

Environment:
Qlik Sense Enterprise all versions

 

 

Resolution:


Check what the port is bound to by going to a command prompt and type:

netsh http show ssl


This gives you a list of bound ports. The list will look like this:

 

SSL Certificate bindings:
-------------------------

    IP:port                      : 0.0.0.0:4242
    Certificate Hash             : f00d5250bc7437265570e162a1a0e89652580614
    Application ID               : {267c44fb-ea4f-46fc-b333-5a4ce8a23381}
    Certificate Store Name       : (null)
    Verify Client Certificate Revocation : Enabled
    Verify Revocation Using Cached Client Certificate Only : Disabled
    Usage Check                  : Enabled
    Revocation Freshness Time    : 0
    URL Retrieval Timeout        : 0
    Ctl Identifier               : (null)
    Ctl Store Name               : (null)
    DS Mapper Usage              : Disabled
    Negotiate Client Certificate : Enabled
    Reject Connections           : Disabled
    Disable HTTP2                : Not Set

 



Find port 4244 and copy the line after IP-address, should look like this:

0.0.0.0:4244


To delete the binding type:

netsh http delete sslcert ipport=0.0.0.0:4244


This will return:

SSL Certificate successfully deleted


Next, type:

netsh http show urlacl


Find port 4244 in the list

Copy the reserved url, should look something like

https://+:4244


Write up the following command:

netsh http delete urlacl url=”copy in the result form above”


For a list of all netsh commands see: https://docs.microsoft.com/en-us/windows/desktop/http/netsh-commands-for-http

 

Cause

 

Port 4244 is bound to another IP address, or a different URLacl.
