Hey,
I was using cyberghost OpenVPN with GL.iNet GL-AX1800(Flint) WiFi 6 Router and it was working fine until recently. I chatted with cyberghost support and did everything they replied, exactly the same as in this post.
However, I am now seeing a new error and wondering if anyone has some thoughts.
