Doc Text:	Cause: The access to an external network provider is enforced to be serialized be non-blocking locking.

Related operation on provider with the id c38a67ec-0b48-4e6f-be85-70c700df5483 is currently in progress. Please try again later." because of the automatic synchronization holds the lock. Fix: Use blocking locks to Import, Add and Remove external networks. Result: Network is added successfully after the sync is finished.	Story Points:	---
