Scenario: 

After updating the user name and password in the login screen system prompts “QLS connection failed! Please make sure QLS running and verify your QLS server IP/port number.  

 Error Details: The host failed to connect. Timeout occurred 

 

 

 

Solution – Database at QNE Cloud Server 

 

If your database is hosted at QNE Cloud Server, just like the sample below
 Please check the Antivirus program on the computer. Basically, it has been blocking the connection. 

 

You can try to turn off the Antivirus program first and see whether can log in or not. The turn-off step is just to determine if the blocking is caused by the Antivirus program. If you can log in after turning it off means you need to add an exclusion in the Antivirus program. 

 

Besides, you may check the Firewall in the computer as well.
 Turn off or add exceptions in the Firewall as well 

 

 

 

Solution – Database at Local Area Network Environment   

 

If your database is stored at the server (LAN), just like the sample picture below, the system will show the server’s name \ followed by QNEBSS. 

 

 

Then you need to 

  • Turn off / add an exclusion in the Antivirus program
  • Add exclusion for QLS in the server
