AS6204 getting error 5039

[Belak]

Here is the situation.. Have used my AS6204 for a couple of years, recently upgraded drives and started from scratch by defaulting the NAS.

I have updated the ADM version to 3.2.7.RRE3

I have issues trying to install any apps to my NAS now. when I click App Central I get a blank box, nothing listed for any of the tabs on the left, (All apps, Asustor Apps, etc) I can download apps manually to my desktop and install on the NAS, but if I attempt to download directly via ADM, it is as if the NAS cannot see the network/internet outside. I am able to ping the NAS on the network and access it via mobile phone/tablets/PCs on the network fine.

System consists of the following -

CenturyLink Fiber 1gig symmetrical WAN connection
Unifi USG4-Pro
Unifi 24-250w POE switch (have 2 ports set to 802.3AD for my NAS)
AS6204
various other devices via wifi/LAN

Any suggestions? I have tried disabling the LAG thinking that maybe it was causing issues, and it still has the same results. I have static IP addresses set for the NAS on my network, and have tried using different DNS services of OpenDNS, Google, my gateway, etc.

Did you check ADM web page -> Settings -> Registration? Any errors?
