OK. I have fixed this issue on my EX2 Ultra. It’s a weird solution and I don’t know where the true root cause is, but this is what I have to do when this happens to me.
- Hibernate (shut down my NAS)
- Physically change the Ethernet port the NAS is connected to my Broadband Internet provider’s router
- Reboot my Broadband Internet provider’s router
- Start my NAS
After that process, I am able to see the application list over the Internet AND I am able to accept the Licensing Terms and Conditions, necessary to manually install an application (like Plex).
My Internet provider uses a Technicolor DPC3848V DOCSIS 3.0 Gateway. It’s 4 port Ethernet and 1 WAN (cable - coax). I have 3 devices plugged in (including my NAS), so it’s fairly easy for me to swap the port. I tried playing with the UPnP setting and other port mapping features and none of that worked. Weird.
