Hi
We are using Nginx as a reverse proxy, connected to a Jenkins continuous
integration server, to provide https access. Jenkins and Nginx run on the same
Linux server.
A certain Jenkins function is failing when accessed via https. It works
correctly when accessed via http (without nginx). Therefore, we suspect that
something is wrong with our Nginx configuration.
In the failure condition, the browser (Edge) shows (in Developer Tools Console):
POST https://jenkins-temptest.<snip>/pipeline-syntax/generateSnippet 500
I don't know how to access the contents of the 500 reply.
Our /etc/nginx/nginx.conf contains:
user www-data;
worker_processes auto;
pid /run/nginx.pid;
include /etc/nginx/modules-enabled/*.conf;
events {
worker_connections 768;
# multi_accept on;
}

# server_tokens off;
# server_names_hash_bucket_size 64;
# server_name_in_redirect off;
include /etc/nginx/mime.types;
default_type application/octet-stream;

error_log /var/log/nginx/error.log;
##
# Gzip Settings
##
gzip on;
include /etc/nginx/conf.d/*.conf;
include /etc/nginx/sites-enabled/*;
}
Our /etc/nginx/conf.d/ssl.conf contains:
server {
listen 443 ssl http2;
listen [::]:443 ssl http2;
# ssl on;
ssl_certificate /etc/nginx/certs/jenkins-temptest.pem;

proxy_connect_timeout 90;

proxy_request_buffering off; # Required for HTTP CLI commands in

}
location ^~ /script {
return 404;
}
location ^~ /manage/script {
return 404;
}
# index index.html index.htm;
}
Is anything obviously wrong with these?
Best regards
David
