Unable to set PuppetCA autosign for ...

The proxy is responsible for writing host entries to Puppet's /etc/puppet/autosign.conf file while provisioning, so they get automatically signed during the build process. This means the foreman-proxy user must have write access to the file - usually it's owned by "foreman-proxy", group "puppet" and with mode 0664.

-rw-rw-r--. 1 foreman-proxy puppet 0 May 14 16:26 /etc/puppet/autosign.conf

If relying on group write, ensure foreman-proxy is a member of the puppet group (and restart foreman-proxy after doing this) and you may need to add this line into puppet.conf to ensure it remains 0664:

    autosign       = $confdir/autosign.conf { mode = 664 }
