RS300 not updating dynamic DNS

Ports forwarded in Xfinity router

37000-37001 TCP/UDP

35000-35001 TCP/UDP

12973-12974 TCP/UDP

All port forward definitions are to the Netgear RS300 Router

Ports 12973-12974 are for VPN on RS300

Ports 37000-37001 are routed from RS300 to Lorex 16 camera NVR

Ports 35000-35001 are routed from RS300 to Lorex 8 camera NVR

R8000 is in another room to provide wifi connectivity for Generac and better wifi in front of house

Lorex has a free DDNS Service and I have 2 through them, each is up dating correctly

Before I bought the RS300 the R8000 was sitting in its place with a NO-IP DDNS definition working correctly, I replaced the R8000 with the RS300  for a faster router and 6G  wifi, I haven’t been able to get DDNS to work.

I only added the R8000 back on my network because the Generac wouldn’t connect reliably to the RS300.

Also if you look at all replies in this chain pkaytes replied that he has a RS500 with the same issue

“I have the RS500 (fw: 1.0.1.90) and can attest that a.) The status function fails 99% of the time and b.) that the router does not send periodic updates to the DDNS provider. I've reported the symptoms to NG but so far there's no fix.”

As a test I unchecked DDNS on the R8000 router then rebooted, next I tried show status on the RS300 and got same error, next I changed RS300 DDNS definitions working DDNS with working definitions from R8000, rebooted and show status failed, next I set DDNS Service Provider to NETGEAR and followed steps to create a free No-IP account, created a new DDNS host name / userid / password and tried in RS300 – Show status failed, as last test I put latest host name / userid / password in R8000 and Show status worked correctly.

Read through the DDNS section of user manual (starting on page 145) to see if there was something I missed but didn't see any thing
