The Communication Type defines how the interface receives and sends messages. If there is a multi-property setup Communication Methods are available for each property. Check and verify if the settings are set for each property. Communication Types can be configured at Global (Chain) or Property levels. When there is a configuration available at Property level, a communication happens with the configured details for that particular property. If not, the communication happens with the configured details at the Global level.
The communication method has to be set up for each interface before it can be activated.
