# fallback dial (for non-Telegram TLS) bypasses HAProxy and doesn't
# loop back here.  Without this, mtg resolves the secret's hostname
# via DNS, which in this setup resolves to this server -> HAProxy ->
# mtg again.  See README's "Fronting loop" section for the long form.
# Requires mtg >= 2.4 (#480 added hostname acceptance for the target).
