Windows 11 22H2 Agent "API Error:Error running automation call <tt>diag-host</tt>"

Removed, recreated, but still the issue persists. I’m not sure why it’s calling the agent_vsphere upon diagnostics: just added the new host, specified the IP, and went for the testing phase. On the host, I did call the agent register which succeeded:

But when testing on the monitoring site, it still returns the same error

API Error:Error running automation call <tt>diag-host</tt>: Your request timed out after 110 seconds. This issue may be related to a local configuration problem or a request which works with a too large number of objects. But if you think this issue is a bug, please send a crash report.

And when calling the cmk debug, it still defaults to the agent_vsphere for some reason…
