Installations with day-1 networking configurations fail on ironic

Installations with day1 networking configuration fail to contact ironic API, on both 4.10 and 4.11.
This is regardless of whether I am using the manual no-dhcp workaround or the bootstrapExternalStaticIP field.
Following the steps in this guide.

Cannot ssh to bootstrap after installation fails.

This failure can be caused by incorrect network/proxy settings, inability to download the machine operating system images, or other misconfiguration. Please check access to the bootstrap host, and for any failing services.
