UPnP issue with Readynas surveillance after 6.5.1 upgrade - connection to cameras lost every minute

[MacRory]

I have a

- RN516 v6.5.1

- R7000 router 1.0.7.2

- ReadyNas Surevillance 1.4.2

all on current releases

i am getting email alerts that the Connections to my three ip cameras is being lost every minute.  

Since upgrading the NAS to 6.5.1 I am getting messages in my router log pointing to the NAS stating:

"UPnP set event: Public_UPNP_C3] from source 192.168.1.XX". I added the XX to block out my ip for the NAS. 

On Readynas Surveillance the logs shows at the same time stamp:

"Connection lost: Camera 1"

then seconds later 

"Connection restored: Camera 1"

this will go on for hours then stop for hours then start all over again with a few sporadic event in between. Nothing is starting at the times this occurs. No DOS attacks are being posted n the router. No errors are occurring for her services running on the NAS such as backups, or Plex. 

I have restarted all all the equipment. Reconfirmed all firmware is current. No other items have been changed EXCEPT the upgrade to 6.5.1. Readynas516 logs show nothing. 

HELP!

Hi MacRory,

Could you send in your logs so we can look at your system? What are the model/s of these cameras are we talking about?

Looking forward to your response.

Kind regards,
