I understand that the question is more appropriate for nginx group, but still... Does anyone have a _working_ nginx.conf file that does the job?
I ended up with 404 from nginx sending gRPC requests (yes, valid requests, verified) with the following nginx.conf:
worker_connections 4096; ## Default: 1024
upstream ip-10-100-30-92 {
server ip-10-100-30-147:50101;
server ip-10-100-130-12:50101;
server_name ip-10-100-30-92;
This file produces 404 response and a line in /var/log/nginx/access.log:
192.168.13.238 - - [29/Aug/2017:16:56:34 +0000] "PRI * HTTP/2.0" 400 173 "-" "-"
Actually, I try to use SSL, and a _working_ example of nginx.conf would be _really_ appreciated.
