Remote Access not working

I am using a remote access node so that I can view my UI with the remote-red phone app. This was simple to set up and worked fine for a few weeks.
Now I am seeing "Error Communicating with server" under the node and now the Node Red UI dot on my phone is red not green.
Indications are that the server on line is no longer working. Is this something I have done or is there an outage somewhere?
The error I get from the node is as follows:
