Hi,
I am running into an error with my Nginx config after following a tutorial on deploying Rails w/Nginx, Puma, and Capistrano.
New versions of the app deploy successfully to the server, however, when I request the droplet’s IP address, I get the following error (according to the Ngninx error log):
2019/11/26 02:49:35 [info] 11483#11483: *9 client sent invalid method while reading client request line, client: xx.xxx.xxx.xxx, server: _, request: "??"
How do I go about debugging this error?
Below is my Nginx config:
upstream puma {
server unix:///home/deploy/apps/modernpricing/shared/tmp/sockets/modernpricing-puma.sock;
}
server {
listen 80 default_server;
listen 443 default_server;
server_name _;
ignore_invalid_headers on;
root /home/deploy/apps/modernpricing/current/public;
access_log /home/deploy/apps/modernpricing/current/log/nginx.access.log;
error_log /home/deploy/apps/modernpricing/current/log/nginx.error.log info;
location ^~ /assets/ {
gzip_static on;
expires max;
add_header Cache-Control public;
}
try_files $uri/index.html $uri puma;
location puma {
proxy_redirect off;
proxy_pass http://puma;
}
error_page 500 502 503 504 /500.html;
client_max_body_size 10M;
keepalive_timeout 10;
}
And here’s the /etc/nginx/nginx.conf file
user www-data;
worker_processes auto;
pid /run/nginx.pid;
include /etc/nginx/modules-enabled/*.conf;
events {
worker_connections 768;
# multi_accept on;
}

# server_name_in_redirect off;
include /etc/nginx/mime.types;
default_type application/octet-stream;

Hey @KDSys, thanks for offering your help here. I appreciate it.
It looks like my issue was rails-specific as I was able to get past this error by changing
force_ssl = true
toforce_ssl = false
in my config/environments/production.rb file.Of course, the other option is to enable SSL for nginx and the app. That’s up next :)
your are missing ssl in:
it should be:
Hi @jmarbch,
I have a few suggestions to help you resolve the issue. First one is quite the long shot however you didn’t specify a server_name in your server block.
Additionally, if you try with a blank index.html file is the same error returned? I’m asking as I’ve seen this issue before and it was actually being caused by the application rather than a problem on the server level.
Regards, KDSys
