Testing a proxy
This error typically means your proxy is offline or not working properly. Don’t worry – we’ve got multiple ways to fix the issue.
Test your proxy
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?

➡️ To test a proxy in Multilogin, select the browser profile or Android cloud phone → click “Check proxy” in the top menu → review the result.
- “Proxy check passed” – Multilogin connected to the proxy and retrieved the required connection data
- “Proxy check failed” – Multilogin could not connect to the proxy; check the traffic balance, connection details, and provider status
Testing your proxy outside the app helps determine the root cause of the issue:
- If the proxy works outside Multilogin, 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
Check proxy traffic
Multilogin proxy
First, check the proxy traffic in the bottom-left corner of the app.

Then, top up your Multilogin proxy, if the traffic has run out.
Your proxy traffic may show a negative value (for example, -1000 bytes). It also means that the traffic has run out.
Proxy traffic is available as a paid add-on. Pricing depends on the package you choose, so check the current options when you top up.
For instructions, see how to add proxy traffic in Multilogin.
VAT may be applied to proxy packages depending on your location and tax status.
Custom proxy
Contact your proxy provider to check the current amount of traffic and top it up if necessary.
Check proxy connection status
If your proxy has enough traffic, test if it's online. Here’s what the results mean:
- ✅ Proxy check passed: Multilogin connected to your proxy and got everything it needs
- ❌ Proxy check failed: the root cause found, your proxy is offline – replace it to continue working in this profile or get a new IP
Select a profile from the list and click “Check proxy” in the top menu. If you use Multilogin proxy, you can also click “Refresh IP” to get a new IP from the same pool. These options are also available in the right-click menu.

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!

Restart the app
The issue might occur because of the app glitch. Restart the desktop app 🖥️ or reconnect the agent, if you're on the web interface 🌐.
Check third-party apps
Some apps on your computer, like antivirus programs, firewalls, VPNs, and proxy tools, can mess with Multilogin. These apps might stop Multilogin from working right or make things run slower.
Here are some quick fixes:
- Uninstall these apps
- If you do need them, disable the apps temporarily or add Multilogin to their whitelist in the settings
This should help resolve the issue and keep everything running smoothly!

- Open “System Settings” → “Privacy & Security” → “Security”
- Click “Open anyway” for the apps
We recommend to change “Allow applications from” value to “App Store & Known Developers”.

Antivirus apps
- Go to “Finder” → “Go” → “Application”

- To turn off an extension, deselect its checkbox
Check the ISP
Sometimes, internet service providers (ISPs) block proxy providers or even Multilogin itself. Here’s how to test and work around it:
- Try connecting through a VPN: this can bypass ISP restrictions
- Switch networks: use a different Wi-Fi, or turn your phone into a hotspot with mobile data
- Check your speed: if your current ISP is slow, changing networks might also improve performance.
If the issue resolves with these steps, it’s likely your ISP causing the trouble.
