I don't think this bug is a duplicate of #1930414, or at least the fix for #1930414 (https://opendev.org/openstack/neutron/commit/9d5cea0e2bb85b3b6ea27eb71279c57c419b0102) does not fix this issue.
I have reproduced the issue on a Wallaby OpenStack deployment which has the backported fix applied.
My workaround is to disable IPV6 on the controller nodes via sysctl (net.ipv6.conf.all.disable_ipv6: 1)
