Proxy Checker: Check Your Proxies Online
Updated:
Paste up to 100 proxies in the form above, one per line as ip:port:user:pass, and the checker tells you which ones work, which exit IP they use and how fast they respond. Below is how to read the results and what to do when a proxy fails.
Format: ip:port or ip:port:user:pass. Passwords are only used for this check and never stored. http:// socks4:// socks5:// (max 100 lines)
How to use the proxy checker
- Copy proxies from your provider's dashboard. With VinaProxy, they are under Orders.
- Paste one proxy per line in
ip:port:user:passformat, up to 100 at a time. Larger lists can be checked in batches. - Start the check and read each row: working or not working, the exit IP and the latency.
Understanding the results
A working proxy shows the exit IP that websites will see. For a static proxy this should match the proxy's IP. Latency is the round-trip time from our checker through the proxy; it depends on distance, so a proxy in the UK will usually show higher latency than one in Singapore. When a proxy fails, the error tells you where the problem is.
| Result | What it means | What to try |
|---|---|---|
| Working | Connected and authenticated | Use it; confirm in your profile with What is my IP |
| Timeout | No answer in time | Re-check later; check if the proxy has expired |
| 407 auth failed | Username or password rejected | Copy credentials again; watch for spaces or wrong order |
| Connect failed | Could not reach ip:port | Check IP and port typos; the proxy may be expired or down |
What to do when a proxy fails
- Check the order status and expiry date in the dashboard. Expired proxies stop accepting connections; renew before expiry to keep the same IP.
- Make sure the line format is exactly
ip:port:user:pass, with no extra spaces or characters. - If it works here but not in your app, the app setup is the issue: choose HTTP as the type and enter the username and password. Then open What is my IP inside the profile.
- If a VinaProxy proxy still fails, open a support ticket with the failing lines. Technical failures are covered by our refund policy.

Frequently asked questions
Is the proxy checker free?
Yes. It is free to use, and you can check up to 100 proxies per run.
Which proxy formats are supported?
Paste each proxy as ip:port:user:pass, one per line. Lines in other formats may not be recognised, so convert them first.
Why does a proxy work here but not in my antidetect browser?
The profile is usually set to the wrong proxy type or the credentials were entered incorrectly. Select HTTP and re-enter user and password.
Why is latency high?
Latency grows with distance between the checker, the proxy and the target. A far-away location naturally shows higher numbers.
Need proxies that pass the check?
Private IPv4 and static ISP proxies with unlimited bandwidth, delivered automatically within minutes.
