@bender@twtxt.net as the host (eg twtxt.net) determines the canonical url of the instance in generated feed url metadata as well as every hash of every post made on the instance internally, i added this error message to make sure people don’t accidentally set up their instance on localhost :p for testing i set it to localhost:31212 and protocols to ["http"], it’s a recent addition that could definitely do with documenting in the getting started section
