Usually this will work.
Power down ALL Sonos devices.
Reboot Controller or Controllers if you have several.
Power up ONE Sonos and wait for it to appear in your Controller.
Power up additional Sonos, one at a time. I like to wait for them to appear in my Controller but a minute between seems good enough. Make sure to power up your main speakers and wait for them to appear in the Controller BEFORE any Sub or Surround.
You normally don’t have to go that far but some setups seem to get stuck and need the full set of steps.
If everything appears and is working you might avoid the problem in the future (power fail or update/reboot) by using your Router’s DHCP settings to assign all Sonos devices a Static/Reserved IP address. Then do the power-cycle again to get everything synced on the same addresses.
