HTTP server not accessible outside LAN

My Cloud OS 5 Personal & Network Attached Storage My Cloud EX Series

Hello guys, I hope someone can help me…
I set up a site in my ex2 ultra, with phpmyadmin and Joomla, everything working fine in local network, but after forwarding the ports in my router, I can’t access it over the internet. I tried to do the same procedure in my Mac (to check if I was configuring the router in a bad way) using the MAMP tool, and it worked fine - both on local and internet access -.
This anomaly only happened before I updated to the latest mycloud firmware 5.09.115.
Did WD mycloud closed the ports for HTTP servers? btw, file access and transfer works both inside and outside LAN.
