CS110-48P switches disconnecting from cloud after v01.3.1268 upgrade

Something like this... 3 switches, last couple days been getting disconnection alerts.  Internal network is seemingly unaffected.  Currently none of the switches are visible in Central.

The switches are all still showing v01.2.1091 locally, though when I could briefly see one of them on Central it mentioned a successful upgrade to v01.3...even though the firmware in Central still showed v01.2.

Definitely some oddness.  I was thinking of updating locally, but from your experience, I may hold off.

Briefly saw the switches again.  Was able to catch this screen shot.

All 3 switches showing (correctly)  v1.2.  

What I was seeing that mentioned v1.3 is the bottom "successful" message.

After about 3 hours, 1 of them registered, but not the other.  I ended up kicking off a reboot it again and it registered immediately, completed the reboot, and re-registered after rebooting.  Just odd.

To add some extra info, the firewall at the site stays connected just fine.  Network/Voice traffic works fine over the switches.  This seems to be just related to cloud registration.

Interesting.... today all 3 switches are showing perfectly fine in Central management.  Can easily click on them and see them.

I suspect something was fixed behind the scenes.

Hello there,

Thank you for contacting the Sophos Community.

Yesterday there were some issues reported for a specific region; on what region is your Central account deployed? However, they’re fixed already.

I'm in the eastern US.  Since the reboots mentioned in my post yesterday, the switches have remained connected.  Just poor timing on my part, I guess.  Thanks all.

Hello there,

Thank you for the update.

I ran into this, check the System Time on the switches! Mine was a couple of months off and after updating the SNTP values it started checking in!
