Hi Mike,
Happy to help!
As per checking, we are currently not tracking any issues with Review 360. I also did a quick test on my end by publishing a new project to Review 360, and I can confirm that this completed without any issues.
Since the issue appears to be isolated, try doing a repair of your Storyline 360 installation to see if this helps. You can also try publishing a blank new project file to test if the issue affects all of your project files.
If the issue affects publishing of any project file, please reach out to your IT team and have them check to make sure that you are able to connect to all endpoints listed in this article.
