Steps to reproduce

on any 1.20.1 modpack. attempt to download neoforge. thats it

Other information

being unable to download neoforge 1.20.1 causes modpacks to be unable to load. which prevents certain mods from running. including for example tardis refined. which does not work correctly on forge. but no i must submit a bug report there.
