I have a supernode running the latest nightly build and I seem to be having an issue on the network to my local nodes. I have my supenode connected to my local hap ac2 using a 1 foot patch cord connected between port 5 on both nodes. I have notices that in the last few weeks the link gets so bad that I can not reach the supernode from my local node after a day or 2 and I have to reboot the supenode and all is fine again. I also noticed that my rtt for my local nodes keeps growing. Oddly if I can not connect to the supernode from my local node I can still connect to it from the wan interface. Please see the screen shot of my supernode for refference. Any assistance would be appreciated.

Are your referring to the aforementioned 'hap ac2' as your 'local node'?
Is 'I' you and what device are your using to connect to an AREDN node.
How are you measuring rtt (real time turnaround?) metrics.
I found no 'screen shot' with your post.
