iCloud backup not accessible

I had a REALLY old iphone 3gs that swore it uploaded all my photos to icloud. and, based on the fact that I supposedly have about 2.3 GB of backed up files, I think that's true.

I just can't look at them. Every time I try on itunes, icloud for windows, and icloud.com I am met with either NOTHING, a message that says "icloud can't load",or an empty promise of all my photos and data being stored somewhere.

I get that it's an ancient iphone, but i was doing all i could to make sure if it broke i would have everything backed up.

well, here we are. and I can't access any of it.

Actually, I got one single folder back. so I know it exists, but something is just not running right.

Someone help?
