1. Is this request related to a challenge you're experiencing? Tell me about your story.

I followed the steps at https://docs.dify.ai/guides/tools/tool-configuration/searxng.

1. I modified the setting file at dify/api/core/tools/provider/builtin/searxng/docker/settings.yml,

   formats: [html, csv, json, rss]

   formats:

   • html
   • json # <-- add this line

2. I ran docker run --rm -d -p 8081:8080 -v "${PWD}/api/core/tools/provider/builtin/searxng/docker:/etc/searxng" searxng/searxng at terminal.

( I tired with curl and it worked)

3. When I added to dify, it shows error

HTTPConnectionPool(host='host.docker.internal', port=8081): Max retries exceeded with url: /?q=SearXNG&format=json&categories=general (Caused by NameResolutionError("<urllib3.connection.HTTPConnection object at 0x7f2a9f93e360>: Failed to resolve 'host.docker.internal' ([Errno -2] Name or service not known)"))

I am not sure why this happened. Any one can help?

Also I noticed that I have two locations where there are settings.yml.
One is at /home/jsops/dify/api/core/tools/provider/builtin/searxng/docker and the other one is at /home/jsops/dify/api/core/tools/provider/builtin/searxng/docker/api/core/tools/provider/builtin/searxng/docker.

For both setiings.yml I edited the file and added -json. Still get this Max retries exceeded with url error.

Anyone can help? Please let me know if there is more detailed needed. Thank you!
