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.
