A small but quite powerful Hamachi program is a tool for quickly creating virtual networks, working on the basis of a kind of emulator that allows you to combine computers that are connected to the Internet into a local network system. Despite the fact that in this application it is possible to use the so-called gray IP addresses and organize data exchange according to principles somewhat reminiscent of P2P technology (as is the case with torrents), and failures can occur quite often in it. One of the most common failures is a VPN status error (in Hamachi, the triangle opposite the connection string indicates it). By and large, this error is not particularly critical, but in its elimination it is necessary to pay attention to some important nuances, which are further proposed to be discussed in full.
Summary of Hamachi Errors
In general, if we talk about the appearance of possible failures, almost all of them relate to the impossibility of establishing a connection between computers through an installed client, when the so-called peer node becomes unavailable.
Typically, most experts cite the following situations as root causes:
- no internet connection;
- the application is blocked by all kinds of protective means;
- the virtual adapter is disconnected, installed or updated incorrectly;
- There were crashes in the network service of the program.
As you can see, the situations between themselves can vary quite strongly, but their consequences are always expressed the same way - a VPN status error appears. In Hamachi, this failure can be eliminated using several simple methods. Let's start with the simplest, but very important point that many users do not pay enough attention to.
Proper software installation
We are talking about the first installation of the application on a user computer or about the situation when you update the program by installing a more recent version on top of the old version. And this just can not be done. In this case, a VPN status error in Hamachi appears due to a conflict of new components with those remaining from the previous version.
To fix the problem, you must uninstall the old modification before installation. But using your own tools of the operating system or uninstalling the original application for this is not recommended, since the leftovers will have to be deleted manually, and if you do not get rid of them, conflicts will become inevitable. It is better to use specially created to automate such processes, some Reinst Uninstaller class uninstaller program or its iObit Uninstaller analogue, which removes all residual garbage automatically both in the form of files with folders and as registry entries.
VPN status error in Hamachi: what to do first?
No matter how trite it may look, but very often the most common lack of connection can cause a failure. Users, alas, are not always able to detect a lack of connection in time, because very often, for example, when using a wireless connection, the status of the Internet connection icon indicates that it is, but in fact it may not be. To check its status, simply open any of the browsers available on the computer and go to some resource. If there is no connection, look for a problem with the system connection.
Another point in which a VPN status error in Hamachi is also possible is related to disconnecting the adapter.
In this case, open network connections (ncpa.cpl), and if the connection via Hamachi is disconnected, select it on in the RMB menu. Follow the same steps in the “Device Manager”, where you may need to enable the network adapter itself.
If a problem with the drivers is detected (for example, after an update), in the “Device Manager” simply delete the existing adapter, and then use the installation of old equipment.
Antiviruses and firewalls
Unfortunately, for some reason, most well-known anti-virus programs almost always block the installed application, considering it either potentially dangerous or unnecessary.
In this case, first just turn off the protection for a few minutes, including the main anti-virus tools and the firewalls built into them, and then see if the error has disappeared. If everything is fine, just add the program to the antivirus exclusion list.
Restart adapter service
Finally, the biggest problem is the incorrect operation of the network service of the installed applet, which very often fails for no apparent reason. To resolve the Hamachi VPN status error, the processes of this service will need to be restarted.
To do this, call the Windows services management section (services.msc), find the Logmein Hamachi Tunneling Engine component in the list, double-click the parameter editor, stop the service by clicking the corresponding button, save the changes and reboot the system (although this is not a prerequisite).
After that, repeat the described steps, but with the inclusion of the service. Pay particular attention to the start type field. It must be set to automatically start.
How to fix a VPN status error in Hamachi if all else fails?
In theory, after applying the methods described above, the problem is usually resolved. But we can assume that the “Hamachi” VPN status error in Windows 7 or in all related OSs in such ways was impossible to fix. In this situation, only the complete removal of the program will help, as recommended above, with the reinstallation. A similar solution can be applied if, for some reason, neither the created connection nor the network adapter is recognized by the operating system, and the indicated components are missing at all in the lists and sections intended for their display.
