Primary firewall lost connectivity
I have multiple sites with TZ370's which are all running in HA. A few weeks ago I had 1 primary firewall become unresponsive and I couldn't ping it's management IP. I had to physically power cycle the unit in order for it to come back online. Today, I just had the exact same thing happen at another location. Power cycling brought it back up. These units have been running for a while, only started seeing this happen the last couple of weeks. Any idea why this would happen?
