Upon running the the dev server 0.0.0.0:8000, I cannot see the website loaded in the browser.
While going through some of the reasons why this might happen, I have done the following changes:
ALLOWED_HOSTS = ['*']
Killed all processes on 8000
firewall turned off
The server I am working on is RHEL.

Starting development server at http://0.0.0.0:8000/
Quit the server with CONTROL-C.
//Nothing is displayed in the browser.
Since you specified that it's a remote server, it most likely be a firewall issue,
you need to make sure port 8000 is open, you could test it using netcat as following :
nc -zv -w1 ip port
if the server is inside a cloud you need to add the rule to your cloud console, turning off the firewall in the server won't suffice.
Just in case the firewall on the server wasn't actually off, you could run sudo ufw allow 8000/tcp (For linux user)

Starting development server at http://127.0.0.1:8000/
Quit the server with CONTROL-C.
Firefox gives me this error:
The connection has timed out
The server at 127.0.0.1 is taking too long to respond.
The site could be temporarily unavailable or too busy. Try again in a few moments.
If you are unable to load any pages, check your computer’s network connection.
If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web.
I'm also using wsl1 and vscode remote desktop for wsl and im running this inside a python enviroment
kill $(lsof -t -i:8000)
Use this command in terminal or cmd to kill the process which is already running on PORT 8000.
If this is also not worked for you, then try to runserver on another PORT like so python manage.py runserver 5000 or any other free port
I'm a complete newbie when it comes to networking. I have two PCs on my LAN both running Manjaro. My main aim is to test functionality on a Django server running on one PC, from the other. I am running the Django server on the PC with ip address 192.168.1.138 using the command
python manage.py runserver 192.168.1.138:8000
and in settings.py
ALLOWED_HOSTS = ['localhost', '192.168.1.138']
I can ping 192.168.1.138 from the client PC, and ping the client PC from the server PC. But if I enter the ip address/port into the browser, it fails with
took too long to respond
I don't know if this a separate problem or a manifestation of the first, but when I run NitroShare, I am able to 'see' the PC running the Django server from the PC acting as the client, but if I try to transfer a file, again it times out. I am unable to see the client from the server in NitroShare.
Any suggestions or help gratefully received
Ensure you don't have a firewall running (or that it allows connections to port 8000). Manjaro's docs imply there might be no firewall by default, but in case there is, see https://wiki.manjaro.org/index.php?title=Firewalls
Set ALLOWED_HOSTS = ['*'], don't bother with limiting them.
Run with python manage.py runserver 0:8000 ; the 0 stands for 0.0.0.0, i.e. has the server listening on all network interfaces.
First I would scan with the other PC the open ports of you "Server"-PC, you can do that with tools like Nmap. Make sure you opened the ports of your "Server"-PC at your router interface. Another option could be the launching of the django app in a docker container. Here's the link of the official docker image at DockerHub:

Django version 1.11.1, using settings 'callluge.settings'
Starting development server at http://127.0.0.1:8001/
Quit the server with CONTROL-C.
So far so good, Now my question is, how could I see this in browser, if i simply access http://127.0.0.1:8001/ browser shows "Unable to connect",
if my domain name is say "osho.com", how should see the project interface in browser.Please help.
Run your server on public ip address of server . 127.0.0.1 is a localhost and it will be available within the your system. outside the machine you can't access this ip address.
So you have to run the server on public ip address of server.
This is probably a very basic question. I SSH to my virtual Ubuntu server and start a django webserver running on localhost:

You have unapplied migrations; your app may not work properly until they are applied.
Run 'python manage.py migrate' to apply them.

Django version 1.9.5, using settings 'mysite.settings'
Starting development server at http://127.0.0.1:8000/
Quit the server with CONTROL-C.
The Ubuntu server has a static IP [x.xxx.xxx.xxx] so from another machine on another network I try to access the above website in a browser using that static IP address:
x.xxx.xxx.xxx:8000
But I get:
This site can’t be reached
x.xxx.xxx.xxx refused to connect.
ERR_CONNECTION_REFUSED
So I assume that I cannot access the website like this and that is only available on the host it self even though the host has an external/static IP address?
Edit:
The answer is also in:
https://docs.djangoproject.com/en/1.9/intro/tutorial01/#the-development-server
python manage.py runserver 0.0.0.0:8000
You need to run your web server on 0.0.0.0:8000, then externally you would use either ip or host name to access. Using 0.0.0.0 means the django service would listen to all configured network interfaces.
Check wikipedia on details about 0.0.0.0.
Another answer on serverfault could be helpful.
I'm guessing there's a very simple solution to this, but I searched every forum and setup guide and can't figure it out:
I built a Django/CentOS-6.3 environment on my local server (using VirtualBox and Vagrant). When I startup my server in the vagrant terminal with 'python manage.py runserver [::]:8000' it starts up with no errors.

Django version 1.5.1, using settings 'mysitename.settings'
Development server is running at http://[::]:8000/
Quit the server with CONTROL-C.
However, when I try to navigate to 'http://127.0.0.1:8001' in my browser (I set up port forwarding from port 8000 to port 8001 in my Vagrantfile), the browser just hangs for 5 minutes until it times out, then it returns the message:
> The connection was reset
> The connection to the server was reset while the page was loading.
> ...
This is the exact same message I get from the browser even after I shut down my local server. My computer obviously recognizes this as a forwarded port, because any other port I try (such as 8000) instantly returns an error saying that it can't establish a connection to the server at 127.0.0.1:8000.
With regard to the server files, I have done many similar setups with Django/Ubuntu in the past and have never had any issues, but there must be something different about Django/CentOS that is causing this to happen (or maybe I made a mistake someone in one of my server files). I have followed guides for setting up Django & PostgreSQL on CentOS, too, but to no avail. I'll comment some of the files I have created/edited below.
If anyone has a solution, or even has advice on where to start looking for errors, I would very much appreciate it.
If your network is configured correctly and your django application with
python manage.py runserver 0.0.0.0:8000
and you still can't access your django app from the VM host there is almost certainly a firewall issue. The solution above is good if you are running iptables.
I deployed CentOS 7 on a virtualbox VM from a Windows 7 host. I didn't know that this distribution uses firewalld, not iptables to control access.
if
ps -ae | grep firewall
returns something like
602 ? 00:00:00 firewalld
your system is running firewalld, not iptables. They do not run together.
To correct you VM so you can access your django site from the host use the commands:
firewall-cmd --zone=public --add-port=8000/tcp --permanent
firewall-cmd --reload
Many thanks to pablo v for pointing this out in the post "Access django server on virtual Machine".
the host's "127.0.0.1" is not the same as the guest's "127.0.0.1". Per default the command
python manage.py runserver
listens only to the guest's localhost. You should be able to test it from within the vm (use "vagrant ssh" to login) and run
curl -I http://127.0.0.1:8000/
The host as a different IP. To access the development server from the host you have to start it without ip restriction:
python manage.py runserver 0.0.0.0:8000
Yes:
python manage.py runserver [::]:8000
should be the same. But that's IPv6 syntax AFAIK. Are you sure that the "manage.py runserver" command supports IPv6 by default? I've never used ipv6 addresses w/ django, but looking at the source (https://github.com/django/django/blob/master/django/core/management/commands/runserver.py) there seams to be a flag that the default to False ("--ipv6"). Perhaps that's the "real" problem?
Regards,
For a similar problem,
This command worked like a charm for me
python manage.py runserver [::]:8001
Check your iptables, and stop it. Ubuntu commonly does not open the iptables when it starts.
