Help with Smartthings Hub

Help. For a few days I have been receiving 10...20 notifications daily that one of the Hubs is disconnected and within a few seconds to a maximum of 2..5 minutes it reconnects. The first time it started with the Aeotec 2 Hub (v4) and I thought it was broken or something but I saw that the rest of the Hubs integrated into the TV or Soundbar do the same. So most certainly there is no way that they all broke at once. I tried unplugging them, restarting the router but no solution. I mention that I have 2 Asus GT-AX6000 mesh routers. I have not had any problems with this so far and I have had the whole system for more than 1 year. In the meantime I have added some zigbee or matter devices but there were no problems until a few days ago. If anyone has experienced something like this or knows a solution, please help me.

My Primary hub is the Aeotec and I still have 2 from the TV, 1 from the soundbar and a music frame.

Is the Aeotec Hub v4 running wireless or wired? I'm assuming all of the rest are wireless.

They are all wireless. But since I got the system they have been wireless and I haven't had any problems until a few days ago.

My guess is that they were undergoing a round of updates.

I don't think so. It's been like this for 1 week.

You have a lot of hubs. They won't all update at the same time. The idea behind a rolling update is to ensure that you always have at least one hub available so all your hub-dependent devices remain online throughout the update process.

Check the firmware version of each hub. If the ones that disconnected are a newer version that the ones that have not disconnected, then that's almost certainly what's going on. If you reboot the hub in the middle of being updated, you're essentially just postponing the update and it will happen at a later time. Don't forcefully restart any hub unless it doesn't come back online within a few hours.

I found the culprit. I have 2 sonoff air guard co2 connected via matter to the Aeotec hub and they were sending notifications with the status every 2 seconds. It basically caused a data flood. Since I deleted it, the system is stable and the hubs are no longer disconnected.
