Unable to communicate with Webapp vi NGINX proxy

[kkempster]

Hi all,

New to this board but I've been using the ad2usb and ad2serial for some time. Have taken the dive into using the raspberry PI and have gone through the complete install a few times but still NGINX proxy is not behaving. Post installation I can successfully browse the PI and get the Webapp login. Post that I have no issue logging in and configuring the communication with the ad2usb attached local to the PI.

Post login the performance seems somewhat sluggish but the keyboard does update and provide the status of the alarm system. When I attempt to access the alarm via the keypad and enter a code to reset the alarm it does not respond or get sent to the alarm. All logs look fine, getting good two-way communication with the ad2usb as I've tested it via minicom.

The interesting thing about this is that if I bypass the proxy, NGINX, and connect direct to the application server, GUNICORN, performance is better and have no issues with entering commands on the keypad. I've gone through this install from top to bottom three times and both on the PI platform behave the same way. I performed a ground up install on a Fedora 17 box and have it working fine.

I do notice that the NGINX revision on the PI is not the latest; 1.2.1; and the Fedora rev. is even older but it works. Should I be looking to upgrade the PI to the latest rev or some other revision of NGINX that behaves better.

Any help or suggestions would be great.

Cheers.

For our release we recommend a specific version of nginx due to the websocket support - nginx >=1.6

Thanks. I'll upgrade via source and see how that goes.

Here's our exact configuration for our official raspbian based image:

Code: Select all

VERSION=1.7.4
curl http://nginx.org/download/nginx-$VERSION.tar.gz | tar zxvf -
cd nginx-$VERSION
./configure --sbin-path=/usr/sbin/nginx --conf-path=/etc/nginx/nginx.conf --pid-path=/var/run/nginx.pid --error-log-path=/var/log/nginx/error.log --http-log-path=/var/log/nginx/access.log --with-http_ssl_module --with-ipv6
