Unable to publish page in edit mode, or to insert an image and try to save.  Error "Unable to communicate with server.  Saving not possible at the moment."

This article describes a similar error when an MS SQL issue occurs. Please check whether this is relevant to your case:

Thank you, started reviewing this article and don't think if it applies we are running Cloud version instead of server version of Confluence. 

I should have specified that in my original question.    I have oepned a support issue.  Appreciate the feedback.

I am surprised to hear you are seeing that error in Cloud as it is usually infrastructure related. Opening a ticket for Cloud support is definitely the right move. Best of luck!

Thank you, but that didn't work for us.   Appreciate the feedback, and will keep that in mind for future reference.

Try removing colored text from the page. See if it works. 

I remember not too long ago atlassian reported an issue saving pages with colored text due to some syntax issue they were working on.
