PyCharm - no route to host

创建于 2025年02月24日 03:50

I have a small Python program that calls `response = requests.get(url)` to retrieve a page from a host on the same subnet.

When I execute the program in the debugger, it fails with this message:

Error fetching URL: HTTPConnectionPool(host='192.168.253.158', port=35482): Max retries exceeded with url: / (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x127d51690>: Failed to establish a new connection: [Errno 65] No route to host'))

If I execute the script with `python3 script.py` it works as expected.

What other debugging info could I provide? Many thanks.

Hi there

Thank you for reaching out,

May I ask if you are using local or remote python interpreter?

Would it be possible to send the IDE logs shortly after replicating the issue (from Help | Collect Logs and Diagnostics data)

do you have any proxy in use in your environment to your knowledge ?

Does the issue only happen when you debug the program or also when you run it from Pycharm?

Kind regards

Sorry for the delayed response. I am using PyCharm 2024.3.3 (Community Edition) on my macOS 15.3.1 M3 processor (Macbook air). I am running locally, using Ctl-R to run the Python program. It also fails if I use Ctl-D to start it in the debugger. I do not have any proxies.

This is the code. If I change the URL to use 192.168.253.1:80 (my local router's web GUI), it works.

I don't know how to send all the debug logs in this report - I see the .zip file - which ones are important? Thanks.

import sys
import requests
from pyparsing import htmlComment
from trilium_py.client import ETAPI

def fetch_html_from_url(url):
try:
response = requests.get(url)
response.raise_for_status()
return response.text
except requests.RequestException as e:
print(f"Error fetching URL: {e}")
sys.exit(1)

html_content = fetch_html_from_url("http://192.168.253.158:35482")

print(html_content)

HI Richard

Is it possible to upload the whole .zip file (just one file)?

The issue looks likely a system/network issue so will you please also provide me the output (screenshot) of the following commands:

telnet 192.168.253.158 35482

curl -v http://192.168.253.158:35482

If possible to have a look at a screenshot when running the python file from the PyCharm embedded terminal would be also useful

Kind regards,
