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

I have setup the dify (version 0.15.3) in my local pc and same is deployed to our Dev server as well. but workflow containing code node fails to run in my DEV server due to sandbox network error, though it works fine in my local machine (localhost). we don't have our own sandbox infra in our DEV server.

can we use dify-sandbox from our DEV server somehow through proxy/whitelisting or Do we need to standup our own sandbox infra in our DEV server, to make code node work (if yes, what is configuration for sandbox we need to have and/or what is process around it) ?

Below is sandbox container config in my docker-compose in my local pc and DEV server.

The DifySandbox

sandbox:
image: langgenius/dify-sandbox:latest
restart: always
cap_add:
#Why is sys_admin permission needed?
#https://docs.dify.ai/getting-started/install-self-hosted/install-faq#id-16.-why-is-sys_admin-permission-needed

• SYS_ADMIN
  environment:
  API_KEY: dify-sandbox
  GIN_MODE: release
  WORKER_TIMEOUT: 15
  ENABLE_NETWORK: 'true'

Please refer the attached screenshot for error. Any help in this regard would be greatly appreciated.
