Just to add another as I stumbled on this thread. I only use GeoFency which requires a Cloud connection, my home gear hasn't changed in many, many months.
I was seeing the same issue as I generally update when I see it.
I tried a soft reset and will see if that fixes the issue.
I've never had the issue prior.
It's not a router issue as I have plenty of various monitoring tools and I'm a home worker so I am using my network almost 24x7.
A reboot of the hub seems to fix the issue as I only notice when my garage doors don't close which only happens a few times a day.
I had to swap out my ASUS routers for a TP-Link. I had RT-AX92U's in a mesh. I think this is very OS specific too...but was running the latest. Even if I turned off all the LAN protection features...one just kept taking devices off the local LAN to LAN network. The basis for it doing it is to protect the Local LAN if a device becomes infected.
What it did, after some period of time, is it decided to trigger this for some hosts. I mainly saw it with my Fire Wall Tablets, but I have no idea about its device decision tree for doing so.
The symptom was that locally, say from my computer at some point, I stopped being able to ping or control my tablets from Hubitat... However, from the router I could. Things from the Internet, like SharpTools could still reach the tablet. This is a LOCAL LAN problem only. It took me a bit to nail it down.
A reboot reset this, and things worked again for a while.
This hasn't happened once with the cheap TP-Link router.
I loved my ASUS routers. Hopefully, I can put them back in at some point as my Internet gateway handling streaming services and cameras and have the rest of still hanging off the TP-Link behind it.
I keep a tab open to snb forum just to see which firmware versions might not break my rt-ax95q mesh. Not sure how/why Asus can't figure out their own products
I used to love my Asus routers as well. But random issues that required Router or AP reboots grew tiresome. I switched over to a full Ubiquity UniFi solution and all of those 'random' issues magically disappeared. YMMV, of course! 
Let me join the chorus here. I also had ASUS routers with AiMesh. With sporadic issues that took devices offline.
I replaced them a FireWalla Gold router and a TP-Link WiFi 6E access points in a wired mesh. At some point of time, I may replace the TP-Link access points with something from Ubiquiti. The FireWalla meets my firewall needs and comes with a very friendly UI - so it's staying.
The person I gave my ASUS routers to has moved on recently to another mesh system.
I use asus without aimesh and hardwired back channel via coax.
Hmm, this is interesting.
I have a C7 and a C8, they're on the same network and have worked perfectly for ages. Nothing has changed on my network. As of a few weeks ago I noticed the C7 no longer sees firmware updates. I ignored it, thinking it would iron itself out. I check yesterday and it has not, and I found this thread.
Same story as mentioned above; it's discovered by Find Hubs. All local features are working perfectly. I cannot access cloud dashboards and instead receive:
The C8 next to it continues to see updates and cloud features, operates normally, both hubs communicate with one another via Hub Mesh with no issues.
I went on to both hubs and updated the DNS settings. Previously I had 1.1.1.1, 1.0.0.1, 9.9.9.9 in the box, so cleared that out and rebooted. The C7 then found the 2.3.9.174 update, so I backed up and applied the update to both hubs. Problem solved, I thought. Nope.
The .176 update was released overnight and in that time the C7 had once again lost cloud access and can't see the update. I added the DNS entries I had before back into Network Settings, rebooted, no good. I then cleared those DNS once again, rebooted and... tada!
I'll update them both to .176 now, but if the trend continues I expect the C7 to lose its cloud access again. And to clarify, there are no other network changes happening. My router is staying the same and there are no clashing IPs. The C8 continues to operate without issue.
Can you PM me the hub for the C7?
Is C8 wired or wireless?
Hey, @gopher.ny - just seen this! Will do so now.
They're both wired and the C7 has indeed fallen off the cloud again.
Ive had exaclty the same problem with C7 , it lost cloud connection over the past week and wouldnt see any firmware updates. I tried a soft reset but still the same issue.
Ive managed to fix it by chaging the DNS server settings in network setup.
Please grab 2.3.9.177, it has some relevant fixes.
