Hamachi shows exclamation marks - what to do?

Hamachi is a popular software to simulate a virtual LAN network. For example, this can be the only way to play together with friends from a distance. However, the problem is annoying when Hamachi shows an exclamation mark.

Problem solution: exclamation mark is displayed in Hamachi

If you want to log in to a Hamachi server, but the client shows you an exclamation mark next to it, there is obviously a problem. Unfortunately, Hamachi usually doesn't give you an error message that can isolate the problem, so you'll have to do some tinkering yourself.

• First, restart Hamachi. If this does not help, restart your PC. Many different problems will already be solved by this, so Hamachi will no longer show an exclamation mark.
• Make sure you have the latest version of Hamachi installed on your computer.
• Check if your firewall is set correctly. You may need to manually allow Hamachi to join the virtual LAN network through the server.
• Possibly the servers of Hamachi are down. Then you can only wait.
