Unable to start Qlik Sense Proxy Service (QPS) due to port 80 conflict with World Wide Web Publishing Service

[PadmaPriya]

 

Environment:

Qlik Sense Enterprise on Windows 

Problem:

Qlik Sense Proxy Service (QPS) uses  port 80, and the World Wide Web Publishing Service is enabled. The Qlik Sense Proxy Service (QPS) service fails to start and you see the following error in the Windows Event Viewer:

The Qlik Sense Proxy Service  reported the following error:

>>> (OS 10013) An attempt was made to access a socket in a way forbidden by its access permissions. : make_sock: could not bind to address 0.0.0.0:80

The Task Manager and the netstat command both show that the System process with PID 4 is using port 80.

To view the netstat command output:

1. Open a command prompt as an administrator.
2. Create a text file named file.txt with the netstat command. Type:
   
   netstat -naob > c:\file.txt
    
3. Open the text file with the following command:
   
   C:\file.txt

Cause:

There is a port conflict preventing the Qlik Sense Proxy Service (QPS) service from starting. The Qlik Sense Proxy Service (QPS) service needs to bind to port 80 to run, but port 80 is already being used by the World Wide Web Publishing Service (HTTP.sys driver).

Solution:

If you are not using the World Wide Web Publishing Service, you can disable it.

10. Close the command window.

Option 2: Disable the World Wide Web Publishing Service from the registry

1. Press Windows+R, type regedit, and click OK.
2. Navigate to the following registry key:
