selfupdate: rsync error: error in socket IO (code 10)

[RobertNadot]

macos Monterey 12.3.1
I suppress macports : ​https://guide.macports.org/#installing.macports.uninstalling
I reinstall : 2.2.1. macOS Package Install
The macOS package installer automatically installs MacPorts, sets the shell environment, and runs a selfupdate operation to update the ports tree and MacPorts base with the latest release.

Download the latest MacPorts-2.7.2-....pkg installer from the releases on GitHub. Here are direct links for the latest versions of macOS:

macOS 12 Monterey:
MacPorts-2.7.2-12-Monterey.pkg

install very slow
install ok

port version ok

This is almost certainly not a bug in MacPorts but a problem with your computer or the way that it connects to the Internet.

The error message says that it cannot connect to our rsync server at rsync.macports.org.

Has this ever worked for you?

Are you able to access this server via rsync outside of MacPorts? Are you able to access any other rsync server? Does your network block access to rsync servers?
