I have a python server running on port 8000 on a raspberry pi and would like to make it accessible within the local network, which is currently not working.

The interface wlan0 is configured with the IP 10.0.0.69 and netmask 255.255.255.0.

I can't reach the server within the local network (from a different host):

root@DESKTOP-Lukas:~# curl http://10.0.0.69:8000
curl: (7) Failed to connect to 10.0.0.69 port 8000: Connection refused

I also can't reach the server from the raspberry pi:

lukas@raspberrypi:~ $ curl http://10.0.0.69:8000
curl: (7) Failed to connect to 10.0.0.69 port 8000: Connection refused

The server is running and listening on port 8000:

lukas@raspberrypi:~ $ sudo netstat -tnlp | ack 8000
tcp 0 0 127.0.0.1:8000 0.0.0.0:* LISTEN 743/python

The server responds properly when using localhost:

lukas@raspberrypi:~ $ curl localhost:8000
<h1>Not Found</h1><p>The requested URL / was not found on this server.</p>

The firewall has allow actions for port 8000:

lukas@raspberrypi:~ $ sudo ufw status
Status: active

To Action From
-- ------ ----
...
8000 ALLOW Anywhere
8000/tcp ALLOW Anywhere
8000 (v6) ALLOW Anywhere (v6)
8000/tcp (v6) ALLOW Anywhere (v6)

Your netstat output shows you the problem:

tcp 0 0 127.0.0.1:8000 0.0.0.0:* LISTEN 743/python

Specifically, 127.0.0.1:8000 shows that your web server is bound only to the loopback address 127.0.0.1. You need to either bind it to the actual network interface or, more simply, bind it to all addresses (usually by specifying 0.0.0.0) and it will then be accessible by all other hosts with a route to your Pi.
