Yes, there is a glitch that we need to document more: default source
type for input.http and input.harbor is to expect stereo streams.
Thus, you need to force the type to a mono stream this way:
# Mono input.http
s = (input.http("http://radiopi.org:8080/reggae";):source(1,0,0))
David commented on this and should be a better reference that me

The restart argument was super seeded by a new "on_error" callback.
This callback is executed every time an error occurs. It receives a
string representation of the error that occurred and returns a float.
If this float is positive, connection will be tried again after its
value, in seconds. Otherwise, connection is not retried.
Default callback is: fun (_) -> 3., that is: restart after 3 seconds.
