ERF50-9294 Failed to save: failed to detect boot server

ERF50-9294 [Foreman::WrappedException]: Unable to find IP address for 'foreman.home.lan' ([Resolv::ResolvError]: DNS result has no information for foreman.home.lan)

This happens when Foreman server or Smart Proxy has no valid DNS record therefore the hostname cannot be resolved. The default TFTP server can be overriden by TFTP Smart Proxy plugin module configuration. Set the tftp_servername value to IP address of the TFTP server (Smart Proxy):

[root@foreman ~]# cat /etc/foreman-proxy/settings.d/tftp.yml 
:enabled: true
:tftproot: /var/lib/tftpboot/

Then restart foreman-proxy.

Foreman installer can set this automatically via --foreman-proxy-tftp-servername option.
