Windows Azure Biztalk Adapter Service: There was no endpoint listening at 'XXX' that could accept the message. This is often caused by an incorrect address or SOAP action

When I am working with Windows Azure Biztalk Services. I was encountered one issue as follows:

There was no endpoint listening at https://xxx.servicebus.windows.net/biztalkadapterdemo/event/ that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details.

 After lots of searching online and looking at logs etc it turned out to be a simple solution to just restart the WAS service (Windows Process Activation Service)
