Please check the production.log and the foreman proxy logs. Either the callback to Foreman fails (e.g. some networking issue) so the host is not marked as built or the TFTP change fails for some reason. Also make sure you go through http://projects.theforeman.org/projects/foreman/wiki/Troubleshooting#How-to-provide-enough-info-to-get-help

Hey,

Denis is absent on buisiness so i try to represent him.

Sadly we don't have any errors or exception logged neither in production.log nor in proxy.log.
The provisioning of a CentOS 7.3.1611 host finished without problems. I tried manually to "Inform the build system that we are done" like in the kickstart file and attached the appropriate production.log snippet.

Tell me if i can provide more specific information.

Resolving the provisioning templates shows that we're using '00-Katello Kickstart Default' for this host.
We only added some snippets to this template, we didn't touched the 'foreman_url'.

I think the problem with it is that on 1.15 onward, the template was updated. `foreman_url` resolves to the provision URL, so to get the real one you have to call `foreman_url('built')`.
I believe you can get this fix by updating Katello, but if that's not possible, see the changes here, it's quite small.

Hope this works :)

Based on the name, this template does not come directly from Katello but is some custom version. Therefore it was not updated. Anyway, I agree, foreman_url needs to be changed to foreman_url('built'). Please let us know whether it helped.

Yes, this changed on Foreman 1.15, and Katello 3.4 adapted to it. Glad to hear it's solved!
