Crash report from Server - how?

Hi all!
I am working on a project (4.27.2) which uses BugSplat for crash reports. It is working great, I have proper callstacks and reports on their website.
However, whenever dedicated server crashes, it does not send any report. I am triggering a crash with
debug crash
and running local and remote server with
-log -unattended
Nothing has been send. Is there an additional step for servers to enabled this functionality?
Cheers!
