All uploads failing


I recently created a Nextcloud account using a server provided by Cloudamo. I had a little issues with setup but once all that was smoothed out and I try to upload anything, example is i’m trying to upload a pdf file, it throws up the error of “an unknown error has occured”, same for pictures, and pretty much everything that I’ve tried. I’m very new to this so don’t know my way around it too well so excuse me for my ignorance. Has anyone had these issues? It’s happening via login through my firefox browser as well as the iOS app. I’m on the most recent testflight version of the iOS app.
