Instead of using the Default settings function in the WebUI, I erroneously used the factory defaults button on the rear of my 620. Now the firewall has been downgraded from R77.20 to R75.20 (983003552).
With this firmware I was now unable to automatically reactivate the license, so had to do that manually. But I'm also unable to update the firmware back to the latest 77.20.
WebUI tells me "Connection to Check Point Firmware Upgrade Service failed" and in the system logs is says "[Firmware Upgrade] A connection error occurred".
Any idea why this happens? Did the update url change? Blocked my firewall because it's out of support/subscription (the last did not matter with earlier updates, I was able to update to the latest 77.20) ?
