Failed to register patch agent.

I have no idea what has happened or changed, I just know that 3 days agao, my Sophos Console Server started spitting out the following Event Errors

"PID 3268 : TID 16

Failed to register patch agent. Internal exception information supplied. Version:100 Agent Version:1.0.303.0 Agent ID:44bc8259-c827-4a81-ae69-24c20cbaef75 User Agent:SophosAgent/1.0 (type="spa"; mid="44bc8259-c827-4a81-ae69-24c20cbaef75"; host="SMHR02") Internal Exception:System.Exception: Patch agent version is greater than maximum supported value.Agent Version: 1.0.303.0

If anyone has any ideas I would be grateful, as it is not impacting our Encrypted clients
