Docker Run Error: Flask app crash

[TheCommandCat]

What happend?

Hey, I tried to run this project with Docker and got stuck. There's an error with gethostbyaddr that seems to crash the Flask app, so I can't access it. Any help would be great!

System:

Windows 11 - Version 10.0.22631 Build 22631 Tried running with and without WSL and got the same behavior

exact same here; I'm on Ubuntu 22

same issue here

Same here on Win 10.

OK, following advice from ChatGpt, I changed this file "/usr/local/searxng/searxng-src/searx/engines/radio_browser.py"

and replaced this line

url = socket.gethostbyaddr(_ip)[0]

with this

try:
    url = socket.gethostbyaddr(_ip)[0]
except socket.herror:
    url = _ip  # fallback: use the IP directly

And it worked !

Only for the current container though, the image is still faulty I guess.

Could a maintainer please confirm if this issue originates in the SearXNG engine? If so, I'd be happy to create a PR in their repository. I want to ensure it's not a project-specific problem before I start working on it :)

I got the latest (june 13) no luck ;-(

for _ip in ip_list:
    try:
        url = socket.gethostbyaddr(_ip)[0]
    except socket.herror:
        url = _ip  # fallback

    if url not in servers:
        servers.append(url)

that worked for me, I think. yes, I can access now at localhost:55009 I wonder what I can do...
