Can't access ip 0.0.0.0
Solution 1
I also find it curious that I although the app is running at 0.0.0.0,
I CAN get to it via localhost/127.0.0.1.
That is because the app is not running at 0.0.0.0
0.0.0.0 is just a notation used for 'all IPs, from whereever`.
If the app is running on your own desktop then you can access it via:
- Local host, IP v4 (aka 127.0.0.1)
- Local host, IP v6 (aka ::1).
- The IP on your NIC( in your case: 192.168.1.143 ), assuming you set those to allowed. This is usually done by setting allowed to 0.0.0.0. (aka allow from anywhere).
Solution 2
0.0.0.0 is typically the outside world, or the internet, hence the route from your gateway to 0.0.0.0 Have you tried setting the host web app to your externally facing IP (go to IPChicken.com)? Most routers have the default route of IP 0.0.0.0 netmask 0.0.0.0 as the route out of your network to internet. It means all address's and all subnets.

I am am coding Python (Flask) on Windows 8. To expose a web-app to outside, I have in the past set host=0.0.0.0
Since I have a upgraded and/or installed Hyper-V with Internet access, I am unable to connect to Flask web app using
http://0.0.0.0:5000.
I have tried shutting down Windows Firewall to no avail.
This is the error:
This webpage is not available The webpage at http://0.0.0.0:5000/ might be temporarily down or it may have moved permanently to a new web address. Error 108 (net::ERR_ADDRESS_INVALID): Unknown error.
I also find it curious that I although the app is running at 0.0.0.0, I CAN get to it via localhost/127.0.0.1.
How can I open/enable access to 0.0.0.0?
