I'm deploying my Djano application on a VPS and I'm following the steps in the below link to configure my app with Gunicorn and Nginx.
How To Set Up Django with Postgres, Nginx, and Gunicorn on Ubuntu 16.04
Everything went well with the tutorial (gunicorn and nginx are running) but the issue is that when Im' visiting the VPS through the static IP its showing a white screen that is always reloading.
After checking nginx log I found the following:
(13: Permission denied) while connecting to upstream, client: <client_ip>, server: <server_ip>, request: "GET / HTTP/1.1, upstream: "http://unix:/root/myproject/myproject.sock:/", host: "<server_ip>", referrer: "http://<server_ip>/"
After searching for roughly 7 hours, I was finally able to find a solution to this issue in the Nginx forum:
Nginx connet to .sock failed (13:Permission denied) - 502 bad gateway
What I simply did was changing the name of the user on the first line in /etc/nginx/nginx.conf file.
In my case the default user was www-data and I changed it to my root machine username.
In the top of nginx.conf file is a user name (user nginx;). just add this user in same group that your site or project is. www-data or any is yours. sorry for english.

I am running a website using Django, Gunicorn and Nginx off a Digital Ocean droplet. The website runs fine for about three weeks and then it random stops connecting users to the webpage. When I visit the webpage in my browser it returns:
This site can’t be reached ERR_CONNECTION_RESET
Restarting the droplet fixes the issue, but it will likely happen again after three weeks.
When I check the Gunicorn worker it says its running fine and my Django logs are clean.
Nginx only reported this:
2019/08/31 23:11:56 [error] 28183#28183: *36352 open() "/home/projects/server/mysite/static/img/icon.jpg" failed (2: No such file or directory), client: 66.249.64.149, server: removedurl.com, request: "GET /static/img/icon.jpg HTTP/1.1", host: "removedurl.com.com"
It seems that restarting Nginx fixes the problem.
EDIT:
I just remembered that I have a crontab set up that renews the Letsencrypt SSL certificate, which could be the problem. Here is the crontab command:
0 0 1 * * /etc/init.d/nginx stop && /opt/letsencrypt/letsencrypt-auto renew && /etc/init.d/nginx restart
EDIT2:
The command above is not a great way to go about this, instead I deleted my original letencrypt certification and used the Nginx webserver plugin for Certbot that allowed me to renew the certification through my existing webserver instead of letsencrypt --standalone trying to start up a new webserver on port 80 (which it couldn't)
I currently have a server setup with nginx and uwsgi with django
This error doesn't happen until I try to change my rds instance
my fully error message is
*10 upstream timed out (110: Connection timed out) while reading response header from upstream, client: xxx.xxx.xxx.xxx, server: xxx.xxx.xxx.xxx, request: "GET /load/ HTTP/1.1", upstream: "uwsgi://unix:/tmp/load.sock", host: "example.com", referrer: "https://example.com/"
I was using aws rds (postgres) which works perfectly fine. The only change I made is changing from regular postgres service to aurora postgres I didn't upgrade the db, from regular to aurora. I created a new aurora postgres. I got everything setup...changed host and everything in my django db setting. runserver locally works fine. It does connect to db with read and write. Works perfectly. But when I deploy to server, open up my domain. Anything ui related looks fine but db related, NO. Took awhile then of course the 504 gateway timeout. I went to checkout the nginx error log. That's the error message I found. Googled, tried a few settings other stackoverflow posts suggested such as addingsingle-interpreter = true into uwsgi.ini file. No luck.
Can someone please give me an idea where I should look into for this problem?
Thanks in advance.
try going to your rds instance, check its' security group setting. Happened to me once, too me a while to find out that the security group setting is the problem. I didn't recall setting up the security group but it restricted with local IP
Ok. I'm at the end of my rope here. I had this working, then I'm not sure if it was just coincidence but I set up VNC on the server and it stopped working (followed this tutorial: https://www.digitalocean.com/community/tutorials/how-to-install-and-configure-vnc-on-ubuntu-14-04)
I've got a Django project through Digital Ocean. I followed their tutorial found here: https://www.digitalocean.com/community/tutorials/how-to-set-up-django-with-postgres-nginx-and-gunicorn-on-ubuntu-14-04
sudo nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
cat /var/log/nginx/error.log

I've been scouring all over but I can't find anything that quite matches what my problem seems to be, even though I have a feeling it's just a silly permission thing that got changed somehow.
If there's anything not clear enough above please ask me to elaborate.
I think you made mistake with sock file in your nginx conf file:
proxy_pass http://unix:/home/user/myproject/myproject.sock;
As showed in error log nginx tries to open /path/to/project.sock file. Change it to /home/username/myproject/myproject.sock
I've installed gunicorn, django and nginx as described in this tutorial.
I've developed a function in django that adds a user in my database and it works perfectly!!
Now I've installed CSF (Config Server Firewall) and if I run it csf -r, the same function for adding a user doesn't work.
I see, in the error log of Nginx, this raw:
*2014/06/25 10:11:04 [error] 5396#0: *19 upstream prematurely closed connection while reading response header from upstream, client: 79.35.50.121, server: [MY_SERVER_NAME], request: POST /django/registerClient HTTP/1.1, upstream: [MY_IP_SERVER]:8001/django/registerClient, host: [MY_IP_SERVER]*
I underline that the function work without star csf.
Can anyone can explain to me why I get this problem?
I am trying to add an application to an existing Django project, but once I have done it I get a 502 error.The server is running Ubuntu. I don't think it has to do with the applications code because I got it running on the django development server. It goes away when I take out the app's name from settings.py and restart gunicorn.
Here's a part of the log
2011/07/15 01:24:45 [error] 16136#0: *75593 connect() failed (111: Connection refused) while connecting to upstream, client: 24.17.8.152, server: staging.site.org, request: "GET / HTTP/1.1", upstream: "http://127.0.0.1:8020/", host: "staging.site.org"
Here's the nginx config file.
Nginx Config File
I'm not sure what other information is needed. Not sure where the gunicorn logs are located. My server admin skills are kind of lacking.
Nginx isn't able to connect to your backend (gunicorn) or gunicorn is refusing the connection. You provided no details about the configuration so that's all the help you'll get. You are correct that the application code has nothing to do with it. It's a configuration error on your part.
