unable to publish, check internet connection

Hello,

I am trying to publish a course from Storyline to Review so I can upload it in a RISE course; however, it keeps telling me that it is unable to publish, check internet connection.  I am able to publish from RISE, I am on the internet, I have been able to publish from Storyline just last week.... Has anyone had this issue and what did you do to resolve it?  I have turned my computer off and on, reset everything, etc and I have a project that is due today (of course!).

Thank you for any help you can provide.
