Controller found but unable to connect - Virtual Controller

AhmedElsadek

Hi , I am facing an issue with connection the iot gateway to the virtual controller 
- I check the firewall setting : all are off
-  Abb virtual controller service is running 
- i can connect the server but not the controller 
- i am using VM 

KennyJiang

Do it mean that IoT Gateway is running on VM but RobotStudio is not?

AhmedElsadek

Both the Robot studio and the Iot Gateway on the VM , also in the VM i used the unlicensed version of robot studio

KennyJiang

What is the version of RobotWare for the virtual controller?

AhmedElsadek

Version 6.16

KennyJiang

Do you include the following 2 options inside the system of your VC?
(1) 616-1 PC Interface
(2) 1582-1 IoT Data Gateway

I was including only Iot , now i include the PC interface and still the same issue . 
I restart the gateway and the controller too .

Is the OPCUA certificate from RobotStudio allowed in IoT Gateway server?

AhmedElsadek

yes , it is . i trust it from the iot gateway configurator 

KennyJiang

Is IoT Gateway both installed and used in administrator mode?

AhmedElsadek

yes , administrator mode

When did the 'Controller found but not unable to connect' happen? After scan the robot and click on 'create' button? After click on 'save' button to save added robot? After click on 'start' button to start the server? Is there any popped up window with error or warning messages?

AhmedElsadek

No , no error messages coming
