Is this persistent (does it repeat every time you try to publish)?

Are you using a mirror? Did you set PUB_HOSTED_URL?

Can you try running: https://github.com/dart-lang/pub-dev/blob/master/app/bin/tools/check_domain_access.dart and post the output? That will give us more information about your network.

Running into the same error (for dart pub publish), https://github.com/getsentry/publish/runs/5723389484?check_suite_focus=true
I could reproduce that locally too (macOS), even using dart pub publish --dry-run, tried 2 more times and it worked, the connection was stable (locally only).
