MG charge hub fails to connect

I have an MG Charge Hub. I have followed and double checked all config settings and confirmed the online status (background status is “OffLine”). I have pinged the chargehq server from my router and confirmed its visibility. But the chargehq reports ‘;Never connected’. The router log reports that a connection was sent, but not responded to (along with a DNS IP address). Has anyone else experienced connection problems and suggest a direction for making a connection?
