Matt, This is where it gets interesting. The issue only arises when nginx is used as a reverse proxy for a *clustered* NiFi (within a trusted environment using http). In fact, it even occurs when the reverse proxy upstream points to only one of the nifi nodes in the cluster. Moreover, the problem is limited to importing/uploading a template. Deleting, downloading, and instantiating existing templates works fine.
There is another strange pattern that I discovered. I can get templates to import if I hard-code the scheme header as follows: *proxy_set_header X-ProxyScheme http;* However, when I hard-code the proxy scheme to http, I cannot delete a template after it is uploaded. Below are several of the logs (IPs and DNS were changed for security reasons). *nginx.err* 2016/12/15 01:19:42 [warn] 29377#29377: *16 a client request body is buffered to a temporary file
