Cant authenticate

It always ends with 503 service temporarily unavailable

Same here. From what I understand, (which admittedly is not all that much, lol) it seems to be an attempt from Apple to block certain strings passed by a client to its authentication servers. altstoreio/AltStore#1790

It should otherwise be a relatively simple fix, but unfortunately if my understanding is correct, SideInstaller will remain nonfunctional until this fix is implemented.
