Hi,

Have you tried running a simple CURL from your deploy host (localhost)? Ie:
$ curl -I -L https://releases.openstack.org/constraints/upper/bfd91c04caf498be2bfda0732a2a0f9fa9306e07


As it seems that the issue happens when you try to fetch upper constraints for local cache. 
You can also try using github as an alternative source, by adding to your user_variables following:

user_requirements_git_url: https://raw.githubusercontent.com/openstack/requirements/bfd91c04caf498be2bfda0732a2a0f9fa9306e07/upper-constraints.txt

Hello,

Following the instruction here (https://docs.openstack.org/project-deploy-guide/openstack-ansible/2025.1/) step by step to deploy openstack with openstack-ansible stable/2025.1 release on four computers (Infra1, Infra2, compute1, compute2) with a fifth computer as deployer (localhost)。

During the execution of command “openstack-ansible setup-infrastructure.yml” error pops up and installation broke. The log is as the following:

...

Can anybody please give a clue on what is going on and how to do troubleshooting?

Thanks a lot in advance!
