I wanted to confirm that more people are experiencing this issue, that it's not just some "local" network problem. The problem is that dnf does not respect max_retries option for a repo when mirror manager is being contacted. I have no idea why it hasn't been fixed yet given that it affects basically all dnf users and it also quite significantly affects building in Copr. clime
