How to test a proxy

Option 1: check proxy with Multilogin Option 2: check proxy with browser extensions Option 3: check proxy with local settings

Most profile issues, according to our users, are caused by a malfunctioning proxy. But how can you tell if the problem is with Multilogin or your proxy?

The answer: check your proxy connection.

Testing your proxy outside the app helps determine the root cause of the issue:

If the proxy works outside Multilogin X, the issue is likely with the app
If the proxy doesn’t work anywhere, the issue is with the proxy itself

In this article, we’ll guide you through three simple options to test your proxy and pinpoint the issue. You will learn how to test the proxy both in Multilogin and outside the app.

If your system time is set manually, it can cause connection issues. In this case, sync your timezone with the internet to fix the issue. This simple step often restores normal functionality!

Option 1: check proxy with Multilogin

This is the simplest and quickest way to test a proxy:

Open your profile settings and navigate to the "Proxy" section
Click "Check proxy" or "Get new IP" – this will test the connection

Here’s what the results mean:

Proxy check passed: great news! Multilogin connected to your proxy and got everything it needs. If you still can’t launch the profile, share the error with us so we can assist!
Proxy check failed: hmm, looks like Multilogin couldn’t connect. This might mean your proxy is offline. No stress – keep reading for more ways to troubleshoot

Check proxy

Option 2: check proxy with browser extensions

Want another way to check if your proxy is working? Use a browser extension to test it in a regular Firefox and Chrome browser:

If the proxy doesn’t work in a regular browser (you can’t load any pages), contact your proxy provider for help
If the proxy works in a regular browser but not in Multilogin, let our support team know so we can investigate!

If your proxy doesn’t work in a regular Chrome or Firefox browser, it won’t work in Multilogin either.

No worries, though – your proxy provider can help! They might:

Fix a server-side issue
Provide you with a new proxy
Adjust some settings to get things running

Reach out to them, and they’ll sort it out for you!

Option 3: check proxy with local settings

Finally, you can check your proxy by adding it to your device’s network settings. Then, try loading a website in your browser.

Here’s what to do next:

If the proxy doesn’t work (you can’t load any pages), contact your proxy provider for help
If the proxy works fine on your device but not in Multilogin, reach out to our support team – we’ve got your back!

Windows

Open the start menu in the bottom left corner and click the gear icon
In the “Windows Settings” menu, go to “Network & Internet”

Click “Proxy” in the left panel to access proxy settings

Proxy setup

Automation setup: enable the “Use setup script” option – you'll get the PAC file path in the “Script address” section.

Ensure the PAC file is saved on your computer, and there’s a complete path to it.

Manual setup:
1. Under “Manual proxy setup” enable the “Use a proxy server” option
2. Enter your proxy details into the “Address” and “Port” sections
3. Enable “Don’t use the proxy server for local (intranet) addresses”

macOS

Open your system settings and type “proxies” in the search field

Click “Proxies” in the search results to see a list of proxy protocols

Proxy setup

Automation setup: Enable the “Automatic proxy configuration” option – you'll get the PAC file path in the “URL” section
