Hello all,
the error with R81.10 Take 79 is persisted. I tried some more SK (so https://supportcenter.checkpoint.com/supportcenter/portal?eventSubmit_doGoviewsolutiondetails=&solut...), nothing helped.
Always (and after every failover) the standby is/was without connection/access to the cloud (or generally internet/DNS, @the_rock hint: curl_cli -k google.com brings error (6) "could'nt resolve"). The active cluster member works always fine - just like the standby (as active) after failover.
Noticeable is the breaking of the sessions on failover (I worked on the problem remote/VPN), this was not before with take 78 ... (timeout after failover for about 10-15 seconds only with Take 79).
So I did a rollback to Take 78 (via Gaia), whereby the difficulty was that only the active member could be uninstalled (check before uninstalling requires access to the CP cloud). But the automatic failover works for happiness 😉
It might be interesting to know that the effect - that the standby has no connection to the CP-Cloud (can't do a DNS resolution) - remained even after the rollback to Take 78 was done on one member, only when both members in the cluster were back on R81.10 T78, the spook was over and everything worked again. (without further changes).
When i find out which specific config might have caused this behavior, i'll let you know here.
Thank you for support!
