I see the problem. Not
RFC2324 compliant.
$1:
2.3.2 418 I'm a teapot
Any attempt to brew coffee with a teapot should result in the error
code "418 I'm a teapot". The resulting entity body MAY be short and
stout.
Edit:
Nope, my bad. It's not
RFC7168 compliant!
$1:
2.3.3. 418 I'm a Teapot
TEA-capable pots that are not provisioned to brew coffee may return
either a status code of 503, indicating temporary unavailability of
coffee, or a code of 418 as defined in the base HTCPCP specification
to denote a more permanent indication that the pot is a teapot.
