# A URL that this site can be accessed on. Do not include a trailing slash.

# The address of the interface to bind to.
# If you don't know what "bind addresses" are, the default of "0.0.0.0" is probably good. If you only want NewLeaf to be accessible on this same machine, not from any other networks, then you can use "127.0.0.1". If CloudTube never updates subscriptions, even after you wait for some time, try using "::1".
#bind_host = "0.0.0.0"

# The port to bind to.
