Error 503 patching download

I think they just fixed their infra. I take no credit, but in the future, if somebody is googling this 503 error, you can TRY accessing it with HTTP instead of HTTPS and running it that way. (Make sure to put it in the PoE2 folder as it'll download the ENTIRE GGPK to the current Folder if you run it from somewhere that doesn't already have the GGPK file)

I'm getting different errors, but on PoE1 while patching standalone client. It's either giving a 404, or "Error: Failed writing received data to disk/application(Failure writing output to destination)"
The drive I'm downloading to is working fine(It's my Windows install drive)
I haven't opened PoE 1 in a while on my PC, probably a week or two.

I am getting this same error and it's driving me nuts! Same issue where I haven't played POE 1 for awhile and wanting to just complete my challenges for the league. The main one I am getting is:

"Error: Received HTTP 404 while downloading https://patch.poecdn.com/3.26.0.13/FMOD/Desktop/Act6KaruiDoor.bank"

the last part where it says "Act6KaruiDoor.bank" changes most times I try again. I was able to get it from a 4.23gb patch down to now just 48.23mb left to patch and now get the error immediately
