@badboycxcc Are you still having this issue in 4.8? I just tested it and it seems to be working. I used an HTTP listener with a PowerShell agent on a Windows 11 machine. What was your configuration?

[badboycxcc]

Oh, I haven't tested it yet, please wait. Thank you so much for fixing this, but I'll have to test it before I can tell you how it turns out.

[badboycxcc]

How do I change to connect to vnc?

The command VNC starts the server with some presets. It looks like you are getting it to successfully compile now and getting a task return.
