File URLS don't open, Missing something

Hello guys, tried to manage it myself but failed

When i use the wd app, send the file URL to somebody (to myself for example) when i click on the URL the file doesnt open.

It processes the query in the web browser and i get the server not found.

Lots of users have this problem.

This post worked for me. In the wd my cloud UI, forward port 80 to 80 and port 443 to 443
