I had a similar issue with Hetzner. I host my downloads on a Hetzner cloud machine, and one of my customers reported that they couldn't download updates. Turns out their company used some enterprise security product named "Zscaler" that mis-identified the IP of my Hetzner VM as Iranian and blocked it.

My customer contacted Zscaler, and after a few days they unblocked it.
