Hi,

I have created the following hostname maestros.freeddns.org. I have no issue to access the server behind using the dynamic IP address or the hostname above from my Internet at home.
Also, I can access the server directly via the IP address using my mobile 4G connection, but I cannot access to my server using the hostname maestros.freeddns.org if I'm using 4G. I tried to change my DNS settings on my mobile phone but nothing change.

From my Internet Home Broadband:
- dynamic public IP address on port 80= OK
- dynamic public IP address on port 1194= OK
- maestros.freeddns.org on port 80= OK
- maestros.freeddns.org on port 1194= OK

From my Internet 4G Mobile:
- dynamic public IP address on port 80= OK
- dynamic public IP address on port 1194= OK
- maestros.freeddns.org on port 80= FAIL
- maestros.freeddns.org on port 1194= FAIL

I'm using 2 ports 80 (= for testing purpose, simple text displayed) and 1194 for a personal VPN server I'm running at home.
Each ports are forwarded to their respective host on my network and are tested and working.

Any help/tips/questions will be welcome. Thank you

So, after checking all settings everything was looking correct. I decided to wait few hours. Today it seems working as expected even through 4G. I will keep an eye on this for the next few days/weeks. :)
