Report back to Foreman instance after Salt state run on Smart proxy

I have troubles with report back to Foreman after Salt state run on provisioned host. I can run highstate from Foreman instance with no problem on provisioned host, but Foreman instance don’t receive any report about that from smart proxy. See logs attached.
Foreman and Smart Proxy are 2 different servers.

Expected outcome:
Foreman instance get report from Smart Proxy about Salt states correctly.

Foreman and Proxy versions:
foreman: 1.19
foreman-proxy: 1.19

Foreman and Proxy plugin versions:
foreman-salt plugin: 10.1.0
foreman-proxy modules: discovery: 1.0.3, salt: 2.1.9, templates: 1.19.0, tftp: 1.19.0, dhcp: 1.19.0
