The following errors usually indicate an issue on the proxy provider’s side:

• "Failed to get IP data: can't connect through proxy"
• "Can’t open session"
• "Connection test failed"
• "Error" or "Proxy error" in browser profile status
• The profile is stuck on "Launching" for a long time
• "ERR_CONNECTION_CLOSED", "ERR_TIMED_OUT", "ERR_CONNECTION_RESET" in the browser profile window

To confirm this, try to connect to your proxy through a regular browser.

You can use a browser extension to test proxies in Firefox and Chrome. You can also refer to this article for instructions on how to test a proxy on Windows and macOS. Alternatively, you can provide our support team with proxy details (proxy type, IP, port, username, and password), and we will test them for you.

• If the proxy doesn’t work through a normal browser, reach out to your proxy provider for further assistance.
• If the proxy works through a normal browser, then most likely it is not returning the IP dependent data: Timezone, Geolocation and WebRTC

To set these values manually, first check your proxy IP on whatismyipaddress.com and then follow the steps below.

1. Disable "Fill timezone based on the IP" and define it manually: 
   
2. Disable "Fill WebRTC based on the IP" and put in your proxy IP (or choose the "Disabled" mode): 
   
3. Disable "Fill geolocation based on the IP" and define the coordinates manually (or choose the "Block" mode):
