Command line and SDKs
First check the proxy protocol and listening address configured in your client, then consult the proxy setup guide for your SDK. Some programs read HTTP_PROXY, HTTPS_PROXY, or ALL_PROXY; others require a proxy agent or transport configuration to be set explicitly. Having an environment variable defined doesn't mean the program will use it. Exclusion rules such as NO_PROXY may also send requests directly.
Don't copy proxy addresses from untrusted sources. A local address means different things inside a container, a remote terminal, and the host machine; a loopback address inside a container usually points back to the container itself. To troubleshoot, first identify where the process runs, then check whether it can reach the specified proxy. Redact credentials, request contents, and personal information from logs. Never print full credentials to public terminal logs.
IDE plugins and editors
Cursor and other IDE plugins may use the editor's network layer, an extension process, and a separate sign-in window. After changing proxy settings, reload the window or restart the relevant process as instructed by the product. Then test sign-in, the model list, and an actual generation request separately. A successful web sign-in doesn't prove the plugin uses the same exit IP.
If code completion works but long conversations get interrupted, check streaming connections, device sleep, and network changes. If every model request fails immediately, check the error logs for authentication, permission, or connection errors. Don't disable certificate verification just to get a connection through. For certificates and access policies on corporate networks, ask an administrator to configure them according to organizational requirements.
CI and remote execution environments
CI runners operate in separate environments; your local VPN doesn't automatically route their traffic. Check proxy configuration, DNS resolution, outbound access, and secret injection on the runner itself. Store model keys in CI's protected variables, and avoid printing full request headers in logs. After a run, check that build artifacts don't contain sensitive configuration.
Before configuring a team setup, confirm the AI platform's supported regions, organization policies, and rules for using code or data. VPNBeach supports Windows / macOS / iOS / Android / Linux, with no limit on the number of devices connected at once. These service details aren't a compatibility guarantee for every CI platform, container image, or third-party SDK.
