Technical Tip: 'Something is wrong with certificate or certificate revoked, errorno(19).' after upgrade

FortiWeb might receive multiple alert events as follows. 

Event Log:

v015xxxxdate=2026-03-18 time=11:09:15 log_id=11005401 msg_id=000012432598 device_id=FVXXXXXXXX eventtime=1773803355420628626 vd="root" timezone="(GMT+8:00)Beijing,ChongQing,HongKong,Urumgi" timezone_dayst="GMTa-8" type=event subtype="system" pri=critical trigger_policy="N/A" user=daemon ui=daemon action=update status=failure msg="Something is wrong with certificate or certificate revoked, errorno(19)."

No issue/ impact seen on the FDS update or any other services; only the alert message is generated.

This issue is caused by FDN and FortiSandbox Cloud updating the DigiCert root CA certificate. FortiWeb has not yet merged this change, so when FortiWeb connects to FDS or FortiSandbox Cloud, the connection fails, and the listed error logs appear.

FortiSandbox Cloud connectivity is broken. There is no other side effect, and applying the workaround resolves the issue without any additional impact.

Workaround:

config system fortiguard
    set fortiguard-anycast disable
end

To resolve the issue, an upgrade to FortiWeb versions 7.4.13 GA, 7.6.8 GA, or 8.0.5 GA is required.
