Turns out this was an issue with a proxy configured in local maven settings. We were not observing this issue in CI only on some developer workstations.

This pull request does not have a backport label. Could you fix it @donoghuc? 🙏
To fixup this pull request, you need to add the backport labels for the needed
branches, such as:

• backport-8./d is the label to automatically backport to the 8./d branch. /d is the digit.
• If no backport is necessary, please add the backport-skip label

@mashhurs not sure if mergify backport will work correctly on a merge commit revert? Either way i did a revert in 9.3 #18517
