Can't upload a big file

I was trying to upload a 149 MB flac file, but it failed with "denied" status. It's not my quota since it's my home server and I have 100GB of quota, about 98 of them free. Is it because the file is too big? Is there a way to import this?

If there really is a limitation around 100 MB, I think it's quite a big one. In some genres, such as classical music, it's common to have such big files.

I'm quite new to funkwhale, so is there something I'm missing?
