test_url_to_node_config[https://[::1]:0/-https://[::1]:0-] fails with latest release of urllib3 (urllib3==1.26.13)

https://github.com/urllib3/urllib3/releases/tag/1.26.13

This is the test that's failing:

This is a bug that will get fixed in urllib3 1.26.14. There's no release date yet though, sorry.
