New National Library of Israel issue

[isaacgmayer]

I had been having trouble using dezoomify with the National Library of Israel. For a while usingReferer: https://www.nli.org.il/ and --header as suggested here worked very well, but recently, every time I've tried to download anything I've gotten many different errors, either a 429 (leading to a checkered, incomplete download) or a 415 "no file error." What am I doing wrong and is there anything I can do to fix it?

I've attached a list of the specific urls I want to download, since it's a long list and would clutter up the question if I copied it in.
