There is a known issue in the 2.2.8 release of Tempered Airwall that causes remote Airwall Gateways that find their Conductor using a DNSSRV record to stop being managed by the Conductor.
You can safely upgrade your Conductor to 2.2.8, but do not upgrade any Airwall Gateways configured using the DNSSRV record for the Conductor.
Tempered has a hotfix for this issue that must be installed on the Airwall Gateways prior to upgrading them to 2.2.8. This hotfix ensures these Airwall Gateways correctly save the Conductor URL and persist the setting through the upgrade to 2.2.8.
