One of our UTMs has a single RED15W connected to give one of our road warriors access, till today this worked fine.
A few hours ago, I updated this UTMs to 9.601-5, the update itself did it's job, after reboot the UTM was up and running.
Unfortunately now the RED15W can't establish it's VPN to the UTM. I attached some lines of the UTMs RED log file.
Seems the UTM recognizes the REDs old firmware, but there is no update for the RED or at least it doesn't work.
The RED is trying to reconnect every 2minutes, without success, it's always the same error, "Disconnecting: Firmware update required. Trying provisioning service ..."
Any hints how to fix this (besides doing a new, clean install with an older UTM firmware)?
