Do you have a solenoid valve as well at the tank or a valve on the tank. Also don’t forget it will take a minute or two for the gas to get through initially. If you have an electrical solenoid you will hear it clunk when it open
You have the same gauge and controller as ours on our crafter so the solenoid should be open with the display showing the green lights in your picture. Is there a gas isolator other than this near the hob? Also on our installation the bbq point has a valve by the connector
it isn’t making the clunk sound. There is an isolation switch beneath the hob and another by the bbq point. No gas at either with isolation valves open. Could it be our solenoid is not working as there is no sound?
