  • We have an active-passive HA cluster. When installing v19.0 MR1, the auxiliary firewall starts with no problems and takes over. The primary firewall goes into fail-safe mode. After logging in via MGMT port on the first firewall, the following message appears in the web interface:

    Can't detect the network processing unit or the related ports. The Firewall started in fail-safe mode and is inoperable.

    If I boot the v19.0 GA everything is fine again. Does somebody has any idea?
