The proxy is connected. The platform's indicator is green. Quotes are frozen. Orders time out. Here's the diagnostic sequence.
Check your end first
Firewall or antivirus interrupting the session. Some security tools allow the initial TCP handshake but drop subsequent packets. Temporarily disable the firewall and test. If quotes resume, add the trading platform's executable to your firewall's allow list and re-enable.
ISP shaping or throttling. Some ISPs treat SOCKS5 connections as peer-to-peer traffic and throttle them after the first few seconds. Symptoms: connection succeeds, then freezes after 10–30 seconds. Test on a mobile hotspot. If quotes flow normally on LTE, the issue is ISP-side. The alternate port in your portal (typically on 443) often bypasses this.
Platform not fully restarted. MT4 and MT5 sometimes hold an old connection open after a proxy change. Fully quit the app — right-click the tray icon, choose Exit — and relaunch. Closing the main window does not close the terminal process on all systems.
Check the proxy end
Portal status page. Log in to the portal and check the node status for your account. If your assigned node is degraded, the portal shows it. A node failover to your backup node is automatic, but takes up to 60 seconds to propagate.
Bandwidth quota. If your account has consumed its hard cap for the current billing cycle, new connections are paused. The portal shows your current usage. Hard cap values: Starter 4 GB, Standard 10 GB, Pro 20 GB, Founder 50 no hard cap.
When to stop and re-check the setup
If the portal status shows the node healthy, your quota is not exhausted, and the mobile hotspot test shows the same behaviour, re-copy the credentials from the portal, restart the platform fully, and test on a second network before assuming the relay is the problem. This product is designed to be self-serve, so the diagnostic path needs to stand on its own.
