OLS support for version 22 was included like 2 months ago making it a new development in the CyberPanel ecosystem. I would not recommend any of my clients to use ubuntu 22 + cyberpanel because of unknown issues esp if you are running mission critical apps and systems.
Kindly use an ubuntu 20.04 image or CyberPanel | DigitalOcean Marketplace 1-Click App instead.
