Resource pack isn't being applied

I wanned to add resource pack to my server, I followed all steps correctly, I went through many troubleshooting threads before writing this, and didn't seem to find solution because I did follow all guides correctly.

https://www.dropbox.com/s/ubin…5b/CUSTOM%20NAAP.zip?dl=1

that is the link that I was using, its ~200MB file. It never shows any errors, resource pack just doesn't get applied.

I tried downloading it from dropbox to check if it goes by some unusually slow dl speeds, but that isn't the case as it downloaded within 1min.

PS my aternos username is same as my username here.

Does the resource pack appear in the resource packs folder at least?

No it does not. And friends are telling me its not being applied but server lags like crazy.

Try with another resource pack, maybe that one is just a bit too big

This is the one we wanted, there's no point in having other packs.

It would be easier then to just add to folders in .minecraft

Packs must not be larger than 50 MB.

I downloaded resource pack from dropbox, and it seems like dropbox keeps corrupting all resource packs. That could be the problem. I discovered it by telling friends to download resource pack from dropbox and put them in resource folder, but it didn't work even then.

Really? I saw some people use 1GB files
