How to fix “ERR_CONNECTION_RESET” error
Sometimes you may get the “ERR_CONNECTION_RESET” error when starting a profile.

Testing the 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
How to test a 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?

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

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!

Proxy test is fine?
How to fix profile launch or proxy connection issues
Most profile issues happen because of a broken proxy. Before you do anything else, test your proxy first. Use this guide to check if your proxy works properly in Multilogin.
Once you're sure the proxy is fine, you can move on to the steps below to fix things. Let’s get it sorted!
Check the agent
Look at the top right corner of your screen – see your agent status? It should say "Agent connected".
The agent is the desktop app that keeps things running smoothly. It’s what lets you launch browser profiles. If it’s not connected, you won’t be able to test your proxy in a profile.
Quick tip: disconnect and reconnect the agent. This restarts important Multilogin processes and often fixes the issue. Need help? Check this guide for step-by-step instructions. You got this! 👍
Check 3rd-party apps
3rd-party apps
Apps like antivirus programs, firewalls, VPNs, or proxy tools (e.g., Proxifier, SocksEscort) can interfere with Multilogin.
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!
How to uninstall 3rd-party apps on Windows
Antivirus
- Go to “Settings” → “Privacy & security” → “Windows Security” → “Virus & threat protection”

- Choose “Manage settings” and then turn off all the parameters in the displayed window

Firewalls

Turn off VPN extensions in browser: don't forget to check and turn off VPN extensions that you installed in your browser, for example, Chrome:

How to uninstall 3rd-party apps on macOS
macOS security system
If the application got restricted from the macOS security system, you can access it by the following way:
- Open “System Settings” → “Privacy & Security” → “Security”
- Click “Open anyway” for the apps
It is also recommended to change “Allow applications from” value to “App Store & Known Developers”.

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

- To turn off an extension, deselect its checkbox
Note: restart your devices after using these solutions to ensure all changes are applied.
Check the ISP
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.
Refresh components
Deps
This action is completely safe! It refreshes the app components needed for Multilogin to work smoothly. No data will be lost during the process, so you're good to go! 😊
- Disconnect the agent
- Go to the mlx folder:
- Windows:
C:\Users\%username%\mlx
- macOS:
/Users/%username%/mlx
- Linux:
/home/%username%/mlx
- Windows:
- Delete the deps folder
- Connect the agent to get things rolling
- Start any profile – this will automatically kick off the components download process
Sync system timezone
Timezone
If your system timezone isn’t syncing properly, just follow these steps to get it back on track:
Windows
- Disconnect the agent and log out of your Multilogin account
- Go to your Windows settings by clicking "Start" → “Settings”
- Choose the "Time & language" section → “Date & time”
- Enable the "Set time zone automatically" and “Set time automatically” settings, and click “Sync now”

macOS
- Disconnect the agent and log out of your Multilogin account
- Go to System Settings → “General”
- Choose the “Date & Time” section
- Enable the “Set time and date automatically” and “Set time zone automatically using your current location” settings

Can’t sync the date or time because the “Set time zone automatically” option is unavailable? Go to your location settings and turn on your original location to enable it. Once that’s done, the button will become active.
Windows
- Go to your Windows settings by clicking “Start” → “Settings”
- Choose “Privacy & security” → “Location”
- Enable the options “Location services” and "Let apps access your location”
macOS
- Go to “System settings” → “General”
- Choose the “Privacy & Security” section
- Turn on the “Location services”

Nothing helps?
If you still can't launch a profile, send us your proxy details (IP or hostname, port, login, and password) and logs. We’ll investigate and provide the best solution for you!
