First I thought of timeout, but since it rejects it instantly, it must be something else.
Did you restart nginx after changing the settings? Is there something in the logs?
The rejection ended up being from Cloudflare.
It turns out their free CDN has a limit of 100M upload. I hope this saves someone down the road the trouble I ended up going through with this!

I’m seeing the same issue on an AWS CloudFormation deploy, though my configuration is different and there’s nothing at /etc/nginx/sites-enabled. I’ve apache2 running but am unclear as to what I should mod in /opt//bitnami/apache2/conf/*.conf to bump this limit.
