I've got a cluster of regular appliances (high-end 5000 series) fresh installed in R81.10 a few weeks back suddenly reporting that they can't connect to CP services anymore. All TP blades are red with the message it can't contact to CP cloud for updates.
Now, traffic through the appliances is apparently OK. CPUSE also stopped working (can't connect to Check Point cloud).
The interesting bit is that it happened all of a sudden on a configuration that has been active and quite static for a long time.
Checking the logs, it's full of RAD errors like RAD timeout or maximum RAD connections reached, stopping handling RAD requests.
Failover/reboot didn't help and increasing the default value of 1000 flows to more either. Activating RAD stats show in CPVIEW a lot of RAD expired/missed for a small amount of successful ones.
The FW have internal DNS defined and can quickly resolve public domains. It can also ping public IP's from itself (for instance ping www.google.com).
curl_cli however takes ages to timeout eventually times out. SecureXL off doesn't help, removing/putting back TP blades neither.
FW has ample CPU and memory space.
Traffic to URL like cws.checkpoint.com is resolvable and not dropped by the FW itself. RAD daemon has been restarted.
Contracts have been updated. Licenses are valid. In short I looked up quite a few things about RAD to no avail.
I have a TAC case which has yet to gain traction. In the meantime, any advice is welcome as most RAD SK indicates the issues are fixed in hotfixes or apply to older versions.
