413 Request Entity to Large on Desktop Client Sync

Hello all. So I’ve scoured the forums to try and find a similar issue to me and cant seem to figure it out.

i’ve installed nextcloud in a jail through the official plugin in truenas.

I then setup a reverse proxy to access my data over the internet.

I am unable to sync larger files on my desktop nextcloud client, returning a 413 error each time. Oddly enough I am able t upload large files through the web client and app client on android. Very peculiar error considering a already modified client_max_body_size to 0; to disable checking.

Again only receiving this error in the windows desktop syncing client
