Bridged Gold Se losing static IP, bringing network to a halt

I am trying to figure out what is going on with my Gold SE.

I have a Comcast Modem going to a Ubiquiti Cloud Gateway Max, I have the Firewalla in bridged mode between the Gateway and a 16 port Ubiquiti POE switch. The switch also has my nic teamed Synology NAS, a Windows 2019 server, a Unifi AP 7 Pro, and a trunked SFP link to an upstairs 5 port switch. I have the WAN 2.5 connected to a port on my GW, and the other 2.5 plugged into my switch.

It worked fine for several months, but randomly I would notice loss of internet on laptops or phones. I was unable to ping the firewalla or Ubiquiti equipment. I restarted the Firewalla and things seemed to go back to normal. It happened again a few days later, so I tried swapping out some cables (the previous ones were brand new). It happened a few more times, so I ran a spare LAN cable from the Router to the switch and disabled it on the router side in case the connection stalled while I was away, I could still remote into the router and enable that port and restore my connection. I went as far as setting up a smart outlet connected to the firewalla. When the connection stalled out, I could enable my backup link to get the switch and AP back online so I could reset the outlet, then when Firewalla came back online, I could disable my backup link.

I formatted an SD card with the Firewalla's latest non-beta image and flashed it last night. I set it up from scratch, gave it a static IP, and deployed it the same way as before. Everything was fine until about 6 hours later when it locked up again. I restarted it and it was fine, then did it again at 8am this morning. I found that there was a log section in the firewalla app, and it appears that it might be losing its static IP and assigning itself 0.0.0.0? Once rebooted it seems to get the correct address.

I like the firewalla for the network flows (which Ubiquiti is slowly getting better at as of the last few weeks). I paid a lot of money for this thing before upgrading my network. I am still under warranty. Do I have a bad unit?

I am only doing some monitoring of my devices, and simple add blocking, not really anything else. (Hadn't setup up VPN yet because of the issues).

I can share the logs if that would help?

Does the problem happen only with ethernet devices? or with just wifi devices? if you can't ping the firewalla, can you ping through it to the gateway?

Unable to ping even the gateway. If I take my cell phone off WiFi, I can get to my gateway over the internet but from the firewalla on nothing responds. It’ll be all wired and wireless devices. It’s like it locks up the whole network. Can’t ssh, can’t load webpages, can’t access local files on my NAS, etc. it’s very, very bizarre

Let me create a ticket for you, I assume this problem just happened recently? our developers can take a look and see if there is anything in the logs.

I did go ahead and dump my log file earlier to my cloud storage just in case. It cleared a few days ago before I could look at it.
