rsync: failed to connect to rsync.macports.org: Connection refused (61)
It works fine for me. Maybe there was a temporary server problem? We did have a brief outage on our Trac server earlier today; not sure what happened or if the rsync server was also impacted.
When checking https://rsync.macports.org/releases I see an 404 Not found message. Has this folder been moved or renamed?
That 404 response is normal, because that is not a valid URL. rsync.macports.org is not meant to be used as an http(s) server; it is meant to be used as an rsync server.
