Can't self update with tarball

[jnojr@…]

Outbound 873 is blocked on my network, and there's nothing I can do about it. So I tried to use the tarball:

flamingo:~ joliver.sa$ tail -2 /opt/local/etc/macports/sources.conf #rsync://rsync.macports.org/release/tarballs/ports.tar [default] ​https://distfiles.macports.org/ports.tar.gz [default]

But:

flamingo:~ joliver.sa$ sudo port -d selfupdate DEBUG: MacPorts sources location: /opt/local/var/macports/sources/rsync.macports.org/release/tarballs ---> Updating MacPorts base sources using rsync rsync: failed to connect to rsync.macports.org: Operation timed out (60) rsync error: error in socket IO (code 10) at /SourceCache/rsync/rsync-42/rsync/clientserver.c(105) [receiver=2.6.9] Command failed: /usr/bin/rsync -rtzv --delete-after rsync://rsync.macports.org/release/tarballs/base.tar /opt/local/var/macports/sources/rsync.macports.org/release/tarballs Exit code: 10 DEBUG: Error synchronizing MacPorts sources: command execution failed
