We have noticed reports of difficulty connecting to the TryHackMe network using OpenVPN on Windows. For example, some users haven't been able to use Zenmap/Nmap against deployed instances while being shown as connected.
As a good rule of thumb, the only need to connect to the TryHackMe network is to use tools against instances often not supported on Windows. I.e.,
netcat reverse shells. Moreover, WSL, even though it is Linux, launching OpenVPN as if it were will not work. We encourage the use of Linux as much as possible for compatibility.
If you wish to continue using Windows, please revisit the OpenVPN Connection Guide and ensure you are running as an administrator. If you see messages relating to TLS errors, read this article.
