README.md.Expected Behavior
Entering a query and selecting Web Search with a query such as "What is the weather today" should produce web results.
Actual Behavior
UI displays "No results" and then returns an answer generated purely by the LLM without any web search content.
Steps to Reproduce
In a proxied environment using DuckDuckGo as the search engine. The error logs indicate the issue stems from a call to socket.getaddrinfo() which returns socket.gaierror: [Errno -2] Name or service not known. This appears to be due to that function not utilizing proxies. I can reproduce this error using the following script in a proxied environment:
import socket
addr_info = socket.getaddrinfo("www.google.com", None)
Logs & Screenshots
Full logs are attached, but keeping two snippets which I suspect may be relevant:

It is possible to enable it via monkeypatching. For more details, see:
You can temporarily patch this as follows:

@tth37 commented on GitHub (Apr 17, 2025):
What are your proxy environment settings? It doesn't seem to be an issue related to open-webui.
@jessiewbailey commented on GitHub (Apr 17, 2025):
Yes I mean it seems like it is an issue with the choice to use socket.getaddrinfo() unless I am mistaken and that respects proxies?
The other detail which may or may not matter is this is running in Kubernetes as a non-root user.
@tth37 commented on GitHub (Apr 17, 2025):
I cant reproduce this error in proxied environment:
Maybe check the DNS configurations in your k8s cluster, it doesn't look like to be an error related to http(s) proxy. What is the result when you run
dig www.google.comin your open-webui k8s container?@jessiewbailey commented on GitHub (Apr 17, 2025):

Check your DNS name server at 10.43.0.10, it's not functioning
@jessiewbailey commented on GitHub (Apr 17, 2025):
Apparently this DNS server is only configured to resolve internal addresses and dig does not support proxies. Curl or wget would work.
@tth37 commented on GitHub (Apr 17, 2025):
What's the result of
curl www.google.com -v, does it work?@jessiewbailey commented on GitHub (Apr 17, 2025):
Yes it works (see below) also things like requests or httpx will work within python (correctly picking up the proxy servers):

According to
95f579c, try setting envENABLE_RAG_LOCAL_WEB_FETCH=true? By setting this open-webui may bypass local DNS query (As in your case local DNS server cannot resolve external domains)@jessiewbailey commented on GitHub (Apr 17, 2025):
This seems to be working you are a wiz!!!
