How to fix error “Wrong proxy data”
Running into a “Wrong proxy data” error when trying to launch a profile? Don’t worry – this is usually a quick fix. It means there’s an issue with your proxy, either your traffic is used up or the current IP isn’t working. Let’s sort it out together!

Check proxy
Check proxy
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.
Top up proxy
Proxy traffic is available at a fixed rate of €3 per GB. To top up, check out the guide on adding 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:
- Open your profile settings and navigate to the “Proxy” section
- Enable the “Advanced mode” at the bottom of your profile settings
- Click “Check proxy” or “Get new IP” – this will test the connection
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

Nothing helps?
