We are having the same issue. First noticed on 11/09/2026.
AWX version 17.1.0
Ansible version 2.9.18
We are considering working around it by specifying the github urls in the file as mentioned here: Ansible Galaxy (https://galaxy.ansible.com/) taking very long to respond - #8 by Rene_Rath but sivel said this should not be a permanent workaround.
We have tried version locking the collections and increasing timeouts but nothing seems to have worked permanently so far. The issue is intermittent it seems, with about a 90+% failure rate in our experience.
