VXDIAG VCX DoIP No Device Detected in VX Manager?

Problem:

The vx manager cannot detect my vxdiag vcx plus doip vci. No device is detected and no network (offline). All indicators on the vci turn on ok.

Any idea?

Solution:

Turn off the Windows Defender and try again.

Feedback:

I figured it out. The router had malicious website blocker turned on. Turned it off and now it works.

It ended up being a setting on my eero mesh system that blocks malicious sites. As soon as I turned it off it worked. It would work when on Ethernet because the Ethernet cable was plugged in to the provider modem and not the Ethernet.

If turn off windows defender won't work for you, try solutions below:
