Servers cannot retrieve kickstart profile through foreman proxy

I see a weird error during kickstart (Attached a picture)
This happens 8 out of 10 times on some servers.
When I specify to download kickstart profiles directly from foreman - there’s no any issues.
We don’t have any firewalls between the servers.
We’re running foreman 1.17
No any errors in the foreman-proxy logs
Any helps appreciated.

No picture no help :slight_smile:
