curl fails in CI

[KenyC]

I submitted my package as PR #8900 and some of the tests failed (cf here). It is not clear why it failed but it looks like it's unrelated to my package (failed curl command).

What should I do? (I don't know the first thing about CI so forgive me if there's a naive "just run the checks again" option that I have missed)

see #8900 (comment)

(admittedly the feedback could be better ;) )
