Seems one or two others are having similar issues with remote access through the http://mycloud.com web portal.

Some steps to try. Try accessing the http://mycloud.com web portal using a different web browser, and if possible a different computer at the same location. Check the My Cloud Dashboard settings to ensure the User account your using has remote access permission and that the My Cloud has remote access enabled and it indicates its connected. Use the WD My Cloud Desktop program for Windows/Mac. One could try a 4 second reset or a 40 second system restore to see if that clears the issue.

It may be possible that the configuration of your computer (since you indicated you don’t have install rights) may be interfering (somehow) with how the web browser accesses the MyCloud.com web portal.
