Chrome supports SOCKS5 proxy connections via launch flags or SwitchyOmega. Configure KnoxProxy in Chrome proxy settings for geo-targeted access.
The --proxy-server flag is the fastest way to set a proxy server in Chrome, pointed at KnoxProxy's gateway on port 7000.
# macOS
open -a "Google Chrome" --args --proxy-server="http://gw.knoxproxy.com:7000"
# Windows
chrome.exe --proxy-server="http://gw.knoxproxy.com:7000"
# Linux
google-chrome --proxy-server="http://gw.knoxproxy.com:7000"Change the scheme to socks5:// and the port to 7001 to run socks5 chrome connections instead of HTTP, using the same command syntax as before.
# macOS
open -a "Google Chrome" --args --proxy-server="socks5://gw.knoxproxy.com:7001"
# Windows
chrome.exe --proxy-server="socks5://gw.knoxproxy.com:7001"
# Linux
google-chrome --proxy-server="socks5://gw.knoxproxy.com:7001"Go to chrome://settings/system and click Open your computer's proxy settings. Chrome proxy server settings live at the OS level here, not inside Chrome itself.
This opens Internet Properties on Windows. Under the Connections tab, click LAN settings to enter a manual proxy address and port at the system level.
For proxy auth and profile switching, install the SwitchyOmega extension from the Chrome Web Store.
Create a new profile with KnoxProxy details. The Protocol field accepts HTTP or SOCKS5, matching whichever port you plan to use.
Protocol: HTTP
Server: gw.knoxproxy.com
Port: 7000
Username: your_username
Password: your_passwordClick the SwitchyOmega icon in the toolbar and select your KnoxProxy profile to route traffic through it.
Create additional SwitchyOmega profiles with different country usernames to switch exit locations without relaunching Chrome.
Visit chrome://net-internals/#proxy to see which proxy Chrome is using, then check httpbin.org/ip to confirm the exit IP matches your KnoxProxy country.

}Browser connections stay persistent within a Chrome instance launched via --proxy-server or SwitchyOmega. New tabs typically reuse the same connection and exit IP. To rotate, restart Chrome with a new KnoxProxy country or session username, or switch SwitchyOmega profiles.
| Problem | Fix |
|---|---|
| ERR_PROXY_CONNECTION_FAILED | Verify gw.knoxproxy.com:7000 for HTTP or :7001 for SOCKS5, and confirm Chrome was launched with the correct flag. |
| Proxy auth popup not appearing | Use the SwitchyOmega extension for reliable authenticated proxy support. |
| chrome://settings/system proxy button opens something unexpected | On Windows this opens Internet Properties > LAN settings; on Mac it opens Network preferences. Configure KnoxProxy there, or use SwitchyOmega instead. |
| SOCKS5 flag connects but pages will not load | Confirm the flag uses socks5://gw.knoxproxy.com:7001, not port 7000. |
| chrome://net-internals/#proxy shows no proxy configured | Fully quit Chrome, not just close the window, before relaunching with --proxy-server, since a running instance ignores new flags. |
USER-country-de-city-berlin-session-profile07Order matters -- geo flags before the session flag. The session name is free text; use the profile ID so the mapping is self-documenting. Password stays as issued; no flags belong there. HTTP on :7000, SOCKS5 on :7001, same credentials.
Chrome does show a native popup asking for proxy credentials, but that dialog is unreliable and often fails to reappear on later launches or tabs. Installing the SwitchyOmega extension from the Chrome Web Store fixes this: it stores your KnoxProxy username and password per profile and applies them automatically every time you activate that proxy.
Not natively; a single Chrome instance launched with --proxy-server applies one proxy to every tab. SwitchyOmega gets closer by letting you define Auto Switch rules that route specific domains through different KnoxProxy profiles automatically, so different sites can effectively use different exit IPs within the same browser window.
No. The --proxy-server flag pointed at gw.knoxproxy.com:7000 only affects that specific Chrome instance and any tabs opened within it. Other applications, background processes, and even a second Chrome window launched without the flag keep using their own default proxy settings, so KnoxProxy traffic stays isolated to the flagged instance.
Yes. Launch Chrome with --proxy-server="socks5://gw.knoxproxy.com:7001" instead of the HTTP flag on port 7000, using the same open -a "Google Chrome" --args syntax on macOS or chrome.exe --proxy-server on Windows and Linux. SOCKS5 authentication still is not handled by the native popup, so pair it with SwitchyOmega for reliable credentials.
Go to chrome://settings/system and click Open your computer's proxy settings. Chrome has no built-in proxy settings page of its own; it always opens your operating system's network configuration, whether that means Windows Internet Properties or macOS Network preferences, to set the actual host and port.
LAN settings is the Windows panel for entering a manual proxy server. Open Internet Properties, select the Connections tab, then LAN settings, and check Use a proxy server. Enter KnoxProxy's gateway address and port there to apply the connection system-wide, not just inside one browser tab.
chrome://net-internals/#proxy is a diagnostic page showing the proxy configuration Chrome is currently using. It confirms whether a --proxy-server flag, a system setting, or a SwitchyOmega profile actually took effect, which helps when a KnoxProxy connection seems configured correctly but traffic is not routing through it.
No. Unlike Firefox, Chrome proxy settings always redirect to the operating system's network panel instead of a page inside Chrome itself. That is why a command-line launch flag or an extension like SwitchyOmega are the practical ways to run a proxy server on Chrome without touching every other app.
