Puppet Master not responding

[Naveen Desu]

Hi,

While I was trying to access Puppet REST API [https://<PuppetHost>:8140/production/facts/<ClientHost>], getting the below error.

I am not sure the issue here & could not find any specific log to further troubleshoot. Any help will be appreciated.

Web application could not be started

Environment (value of RAILS_ENV, RACK_ENV, WSGI_ENV and PASSENGER_ENV)
production

PS: The server was working fine until the REST API DELETE https://<PuppetHost>:8140/production/certificate_status/{hostname} was run.

Thanks,

Naveen.

I just had this happen to me today.  Turns out that I had pasted some database settings into the puppet.conf instead of the database.ini while using screen and having too many windows open.  Luckily I had some cert warnings so I ran puppet cert list --all and got an error about the puppet.conf file having an invalid line.  There you go,
