NGINX Reports 413 Request Entity Too Large Error

When you get a client side error during upload either in Cadenza or the devtools with a status code 413 and the message Request Entity Too Large you are most likely running into a reverse proxy configuration problem.

Not just Cadenza has limitations on the size of uploads, but your reverse proxies can also limit this.

In NGINX you need to set client_max_body_size to a larger value. The default is 1m. See the NGINX documentation for this property.
