Check Point Update Services down? -- Connection Error, FDT - Unexpected error code

[StackCap43382]

In process of patching a manager and CPUSE is failing to connect with error:

Connection Error, FDT - Unexpected error code.

According to SK this is a time issue but time is fine (Checked NTP):

https://support.checkpoint.com/results/sk/sk165373

Performed a Packet capture between device and check point services and connection is reset after several change of cipher messages.

Checked other devices and same issue.

Even my lab has the same issue.

Raising ticket with vendor now. 

Anyone else seeing this? 

Cluster is on R81.20 T113 Attempting to patch to T120

I think it is probably related to this:

Certificate and CRL validation fails from March 1, 2026

Second that. Please apply the mentioned workaround from the SK and see if it helps

SK mentions R82 & R82.10 estate is R81.20.

My LAB CPUSE is able to dial cloud services now so looks like an intermittent issue.

Here, it did not help. It might not even be related...

I had the FDT error, starting at 2026-03-01 - 16:08:56 CET on one cluster member and it still occurs after having installed the hotfix.

Now, the other member also had the FDT error in the DA_UI.log, starting at 2026-03-01 - 18:40:48 CET but was able to successfully check for updates again an hour before I installed the hotfix.

Edit: cluster on R82 JHF60.

Hello

if you take a look here https://community.checkpoint.com/t5/Firewall-and-Security-Management/Certificate-and-CRL-validation-... as suggested by @_Val_ try to apply the workaround.

Give it a chance (if not already done).
