ERR_CONNECTION_TIMED_OUT Error when accessing Qlik Sense Qlik Management Console or Hub

[Rakesh_HB]

Accessing the Qlik Sense Enterprise on Windows Hub and Qlik Sense Management Console using the hostname or FQDN, returns the error:

This site can't be reached
ERR_CONNECTION_TIMED_OUT

Accessing either the Management Console or Hub using localhost (localhost/qmc or localhost/hub) works. 

Resolution

The likely root cause is a wrong fixed IPv6 and IPv4 address in the pg_hba.conf file and hosts file. 

• The pg_hba.conf file is located in "C:\Program Files\PostgreSQL\<version>\data" of your PostgreSQL installation path.
  
  

  The paths in the instructions are adapted to a default PostgreSQL installation used as database on a dedicated server. A PostgreSQL database installed by Qlik Sense has the following database path: %ProgramData%\Qlik\Sense\Repository\PostgreSQL\<version>\.

• The hosts file is located in the "C:\Windows\System32\drivers\etc\" folder.

To resolve an IP mismatch:

1. Verify your current IP address using ipconfig in a Windows Command line
   
   
   

   
   fe80::1d08:f195:bee:****** is the IPV6 address

   172.16.16.**** is the IPV4 address

2. Compare the IP addresses to the ones listed in the hosts file and correct them if needed
   
   
   
   
3. Compare the IP addresses to the ones listed in the pg_hba file and correct them if needed
   
   

Cause

When a Windows Machine snapshot restore is performed, the IPs will change, and the network will be routed to old/existing IPs fixed in the above-affected config files (hosts and pg_hba.conf). This needs to be replaced with new IPs.
