Something change with 'proxy_header' since January 2016?

Now gives the following error:
Caddyfile:4 Parse Error: unknown property ‘proxy_header’

Yes, over a year ago, proxy_header was deprecated for header_upstream. :slight_smile: We had warnings in place for several versions. Be sure to always stay up to date!

Thanks! Another way of looking at it is that my caddy server ran unattended for a year and a half without issues.
