### Are you willing to submit a PR?

- [ ] I'm willing to submit a PR!

Reproduce the report with the provided docker run command on Ubuntu 20.04.6 and inspect container logs around the BookKeeper PerChannelBookieClient connection to 172.17.0.7:40643. No source file or test is named; completion would require isolating the refused connection and documenting or fixing the confirmed cause with a regression check.
