A few weeks ago I had problems with the connection to the Tryhackme-network with OpenVPN. I searched around the internet and found different solutions. For me worked the following simple solution. Open your OpenVPN-Config for THM and edit the following line:
cipher AES-256-CBCReplace it with:
data-ciphers AES-256-CBC:AES-256-GCM:AES-128-GCM:CHACHA20-POLY1305Save and close the file and try to connect. On Windows, I would recommend reimporting the config and then trying to connect. You should now directly connect as usual and don’t run into a loop of reconnects.
