Cause:

The error “Connection could not be established to the host“ usually occurs because of following reasons:

1) When the target host is unreachable.

2) When the Vembu Integration Service in the target host is unavailable.

3) When the Vembu Integration Service in the added target host is stopped.

Solution:

In order to overcome this error, please try the below steps:

1) Check whether the added host is reachable.

2) Check the availability of VIS agent

  • Go to 'run' and type control panel
  • Programs -> Programs and features
  • Check for Vembu Integration Service agent

3) Check whether VembuIntegartionService is running in the target host. For this go to 'run' and type services.msc -> check for VembuIntegrationService:

  • If service is in the stopped state then start it manually or else
  • If the service is disabled then, right-click the VIS service and select properties -> change the startup type from disabled to automatic.

4) Check whether 42005 port which is used by Vembu Integration Service is blocked. For this go to 'run' and type control panel -> system and security -> select windows firewall

  • Click advanced settings -> and go to inbound rules
  • Check VIS agent port rule is enabled or not [42005]

If it is blocked state then allow the connection by using below steps:

  • Right-click and choose properties and select allow the connection

If there is no 42005 port then add it manually in the firewall by using below steps:

  • Click add new rule -> select port and click next
  • Select TCP port -> and select specific local ports on that enter “42005” and click next
  • Select allow the connection and click next
  • Select rule apply as both Domain, private and public and click next
  • Enter the name as “VembuIntegrationService.exe” and click finish to add this rule to the firewall
  • Go to Inbound rules again to check whether the new rule is added to the firewall or not.
