So I managed to debug this a bit more and it looks like uWSGI itself is
fine as I can run it directly, but either my nginx or service is causing
the issue.
My service looks like:
[Unit]
Description=uWSGI instance to serve flexlm
After=network.target
[Service]
User=shareef
Group=nginx
WorkingDirectory=/home/shareef/html/flexlm
Environment="PATH=/home/shareef/html/flexlm/venv/bin"
ExecStart=/home/shareef/html/flexlm/venv/bin/uwsgi --ini
/home/shareef/html/flexlm/flexlm.ini
[Install]
WantedBy=multi-user.target
and my nginx config looks like:
server {
listen 80;
server_name flexlm.me.com ;
location / {
include uwsgi_params ;
uwsgi_pass unix:/home/shareef/html/flexlm/flexlm.sock;
}
}
