nginx proxy template has very small max_body_size
Adding client_max_body_size 30m;
to deploy/funkwhale_proxy.conf is required to upload songs via web UI.
Without it requests are not passed through to Funkwhale, and the UI gives unhelpful messages such as "denied" and "error". This was with a docker deployment, but I suppose it applies to any nginx proxy deployment.
Thanks for the great work!
