Firewall has not checked in with Sophos Central

Maybe. the latest release on Central has the ability to change the email alert frequency of a particular alert.

Open the console and drill down into one of them. Under the Actions area you should see and Email Alert box where you can change the frequency.

This might do the trick.

Thanks balletbob,

I have changed Email Alert to "Never" the default setting is "Daily"

We have multiple firewalls and I see that all these alerts come only from the HA setup.

Thanks for posting this.

Almost a week later and apparently no resolution yet though.

Been happening for about a week now with multiple firewalls on our end.  Very annoying.

Hello,

I received the following from Sophos Support about this issue yesterday.

Sophos is investigating reports of some Central customers receiving false positive XG Firewall connection alerts on their dashboard. This issue is marked as BUG with the ID 2046 and our team is investigating on this.

"Firewall has not checked in with Sophos Central for the past (x) minutes"

Please refer the link below for more information on “Advisory: Sophos Central - Some customers are receiving false positive XG Firewall connection alerts”  https://community.sophos.com/kb/en-us/134073 We shall update you as soon as we have further information in this regards from our concerned team. 

Problem still exists on several firewalls

Any updates on this fix?

I saw somewhere where the fix to Central was to occur this month.  Oh here's the KB (tentatively the 15th)...

Can't come soon enough. I'm tired of having to clear fake alerts. 

I know this is silly but I swear on XG every once and awhile I resolve issues by simply restarting each of them.
