Command Line: Confirm the Process Reads the Environment Variables
Some command-line tools read HTTP_PROXY, HTTPS_PROXY or ALL_PROXY; others need an explicit proxy setting or a dedicated connection adapter. Setting a variable does not guarantee that the software uses it. Check your SDK’s documentation for the proxy protocol, local client listening address and scope. Don’t copy someone else’s port settings blindly.
After environment variables change, existing terminals or background processes may still have the old environment. Restart the process making the call, then check its logs. Containers, remote terminals and subsystems have their own network environments, where a local address may not point to the host. Assuming that a successful browser test proves a container is connected can leave this difference unchecked.
IDE Plugins: Test Login and Completions Separately
The editor UI, plugin host and remote development environment may each make their own requests. After signing in to GitHub Copilot or another plugin, check whether model requests come from your local machine or a remote environment. Check the IDE’s own proxy settings, plugin documentation and network diagnostics; don’t assume every plugin automatically inherits the system proxy.
Successful Cursor account authentication does not prove that every model feature and file-related request is working. Start with a simple text task to verify the session, then test the editing features you need. If the error occurs only in a remote workspace, check the remote process instead of repeatedly changing local browser settings. Follow your organization’s network and data-handling policies on managed devices.
CI: Check the Runner, Not Your Development Machine
CI jobs usually run on separate runners, and your local client won’t automatically cover that environment. Confirm where the job runs, whether the service is supported there and whether the runner can reach the target address. Configure any required network settings according to the platform’s documentation. Store keys in CI secret variables, never in the repository, command output or public build artifacts.
Classify failures in automated jobs: fix credentials for authentication errors, check billing for quota errors, and inspect the exit route for connection failures. Use backoff for temporary errors that are appropriate to retry, and avoid resubmitting tasks that incur charges. VPNYet’s unlimited device connections do not mean third-party APIs have no concurrency limits or usage caps.
