a trivial change on our external firewall with a (normal) subsequent sync to the secondary device caused both firewalls to go into “disabled”
state and not forward any packets anymore.
An deactivation and activation of the High Availability solved the problem.
The connection interruption lasted from 11:08 – 11:41 CEST, we apologize for any inconvenience.
We are in contact with the developers to find the rootcause of this issue.
We apologize for any inconvenience.
