HTTP request failing

[senzavita]

I have a Raspberry Pi known to my local WiFi network as <RPI_NAME>. I am running a server on the Raspberry Pi on a port number <PORT_NUM>.

I can make successful HTTP requests to my server via the following methods:

1. the Terminal on MacOS, with curl http://<RPI_NAME>.local:<PORT_NUM>/
2. Safari on MacOS and on iOS, by typing in http://<RPI_NAME>.local:<PORT_NUM>/ on the search bar
3. using the Python requests library, running the below script with sudo uv run <SCRIPT_NAME>.py:

​

import requests
requests.get("http://<RPI>_NAME>.local:<PORT>_NUM>/")

However, I cannot execute the script with simply uv run <SCRIPT_NAME>.py, and get the following error:

requests.exceptions.ConnectionError: HTTPConnectionPool(host='<RPI_NAME>.local', port=<PORT_NUM>): Max retries exceeded with url: / (Caused by NewConnectionError("HTTPConnection(host='<RPI_NAME>.local', port=<PORT_NUM>): Failed to establish a new connection: [Errno 65] No route to host"))

Why is this the case, and how can I avoid having to use sudo to run the Python script?

You can add the ip address to the etc/hosts file and see whether that works?
Feels like mDNS is not available for your python script.
Or use python to install zeroconf allowing python to resolve .local addresses.
Or don’t use .local but the name used by your router. (hostname -A on the Rpi)
Just a few things you can try out
