I'm not able to reproduce it on Elastic Cloud deployment 8.14.1

but maybe it is an issue with specific distro.

I'd like to point out that this elasticsearch/kibana cluster is hosted on a DMZ.
Proxy is added to reach artifacts.elastic.co, for fleet to work. If this feature is also dependent on internet connection, this could be the cause.

Seems related to #186969 (PR)

[maryam-saeidi]

Fixed in #188724, and the fix is available from v8.15.

For now, the workaround is to create/update APM rules using observability > alerts > rules page.
