Whoer.net

Hi so i use whoer.net as a basic check my vpn is working ok test.

a few things came up.

if i connect to a different timezone it can tell despite proxy time (not a major issue).

could be a major issue.
if i am using just the desktop app on automatic port select mode it detects open proxy ports (note this is solved if you manually select ports on the desktop app).

Pay no attention to that site. This is all a scare tactic to get you to buy their VPN. It shows “open proxy ports” on my home connection.

Which service would you recommend for a simple check if it is working properly?

Is there any site? Because up until now i was using whoer.net too eventhough i know that they just want to sell their own service.
