Question

Hi,
My website has been down for 2 months, I've basically given up resolving this issue, I have been talking with DO support as well as posting on stackoverflow and nobody seems to be able to help me.

Setup: 1-click install of django, ubuntu, nginx

Issue: After setting up a domain, visiting that domain results in a 400 error. visiting the IP works with no problem. I purchased the domain using Google Domains and used the custom name server option and put:

ns1.digitalocean.com
ns2.digitalocean.com
ns3.digitalocean.com

In etc/nginx/sites-available/django I have:

upstream app_server { 
server 127.0.0.1:9000 fail_timeout=0; 
}

server { 
listen 80 default_server; 
listen [::]:80 default_server ipv6only=on;

root /usr/share/nginx/html; 
index index.html index.htm;

client_max_body_size 4G; 
server_name cannablr.com www.cannablr.com;

keepalive_timeout 5;

# Your Django project's media files - amend as required 
location /media { 
alias /home/django/django/dealr/dealr/media; 
}

# your Django project's static files - amend as required 
location /static { 
alias /home/django/django/dealr/dealr/static; 
} 

location /favicon.ico { 
alias /home/django/django/dealr/favicon.ico; 
}

location / { 
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; 
proxy_set_header Host $http_host; 
proxy_redirect off; 
proxy_pass http://app_server; 
} 
}


I have this file symlinked inside etc/nginx/sites-enabled.

Another thing that may be worth noting is even though I get a 400 error when visiting the domain, it still loads the favicon.

Any ideas or help would be appreciated.

This has to do with getting ALLOWED_HOSTS correct.
ALLOWED_HOSTS: A list of strings representing the host/domain names that this Django site can serve
Ref: ALLOWED_HOSTS
Correct this in your setting file.
e.g. Django One-click app has settings location: /home/django/djangoproject/djangoproject/settings.py

Add your domain to ALLOWED_HOSTS
```
ALLOWED_HOSTS = ['example.com']
```
At the end of file, one more entry exists for ALLOWED_HOSTS to allow sites to be accessed by DO ip addresses.
```
# Discover our IP address
ALLOWED_HOSTS = ip_addresses()
```
Change "=" operator to "+=", so that it will append ip addresses rather than overwriting
ALLOWED_HOSTS setting.
```
# Discover our IP address
ALLOWED_HOSTS += ip_addresses()
```
If you don't want your Webapp to be accessed by ip address, simply comment/remove second entry.

I believe I may have a solution. I was experiencing the same issue. I checked my settings.py file and at the very bottom I found

ALLOWED_HOSTS = ip_addresses()

I commented it out and everything appears to be working fine.

It seems that digital ocean has added this and the ip_addressses() function to the settings.py file but I do not have a clue as to why yet.

I think this just fixed the problem I've been dealing with for days! Thanks!
1 click install... -.-

yes this works fine
But after commenting out "ALLOWEDHOSTS = ipaddresses()" . you have to specify the domain name in the ALLOWED_HOSTS = ['example.com'] . you can add your IP here as well separate entries with comas.

You need to add your domain name to "ALLOWED_HOSTS' inside of "settings.py" of the django project
