Getting an “Unable to start flow” message when creating new flow in AppConnect

I’m trying to create a new flow in App Connect and I keep getting a popup message that states “Unable to start flow” whenever I click on “Exit and Switch on”.

I’ve tried:
1. Deleting and recreating the flow.
2. Deleting and recreating the Network that is used in the flow. (BTW,,, the old network definition keeps reappearing).
3. Deleting and recreating the Application definitions.

Each attempt at recreating artifacts I’ve tried using different names. No luck.

I have two questions:
1. How do I troubleshoot the “Unable to start flow” error message?
2. How do I permanently delete a Network definition?
