Action server error fallback handling

Currently, the action server errors can be seen in the Rasa server logs.

2021-04-27 12:14:40 ERROR rasa.core.actions.action - Failed to run custom action ‘action_retrieve_faq’. Couldn’t connect to the server at ‘http://localhost:5055/webhook’. Is the server running? Error: Cannot connect to host localhost:5055 ssl:default [Connection refused] 2021-04-27 12:14:40 ERROR rasa.core.processor - Encountered an exception while running action ‘action_retrieve_faq’. Bot will continue, but the actions events are lost. Please check the logs of your action server for more information.

From a chat experience point of view, the user will receive no response. Is there a way to capture the error and handle this using fallback utterances?

are you sure the your action server is running on the port 5055?
