Interestingly, its a URL encoding issue.

The URL that curseforge.com gives you is ...

https://media.forgecdn.net/files/2520/96/inventorysorter-1.12.2-1.13.1+55.jar

But the correct one (which does work) is ...

https://media.forgecdn.net/files/2520/96/inventorysorter-1.12.2-1.13.1%2B55.jar

(The + is correctly encoded to %2B)

Would recommend you don't use + in your filename.

[cpw]

Why not? That is the correct way to encode + and it should be expected, since + is also a get parameter separator.

Curseforge fixed this for you. 👍

It's now (3 days ago this wasn't true) encoding the filename during the final CDN redirect to correct the bad encoding.

Which curseforge.com now sees and fixes the encoding (using the %2B escaping) with the final 302 redirect to the forgeCDN.

Which allows the download to succeed on the next request to the file on the CDN.
