The old https://git.openstack.org/ service moved to https://opendev.org/ as of 2019-04-20. Compatibility redirects are provided at the old name but are on a shared IP address so a client supporting SNI (IETF RFC 3546 section 3.1 "Server Name Indication") is required to see the correct hostname on the redirect. SNI is ~16 years old now (RFC 3546 is circa June 2003), but a number of HTTPS libraries took a while to catch up so may still not support it on some older platforms.
We can look into moving this vhost to a dedicated server/IP address or to be the default vhost on the current address, but backporting any of the master branch fixes for updating to the new URL would be another option if the Python interpreter and/or pip can't be upgraded to use SNI.
