GNS3 2.2.8 VM Connection issue on Win10

GNS3 2.2.8 VM Connection issue

I have downloaded the Gns3 2.2.8 and installed on my laptop. earlier version GNS3 was working fine but just to test new Gns3 2.2.8 with web gui i have installed it. but when i fired up the gns3. Gns3 interface started well and its automatically trigger the vm inside the vmware workstation but it didn't turn up in GNs3 application console Server Summary.

In the serve summary VM is showing red sometimes Gray.

But in the Gns VM was be up and running.

Ping was working as expected.

When i checked the default port in Gns3 Console- Edit- Preferences - default TCP port was 3080.

Changes the default port to 3080 > 80 and apply and ok Gns3 vm rebooted

And Finally Server Back online in the server console in GNS.

So in summary, sometimes your firewall or HIPS block the Gns3 Default Communication TCP port 3080.But changing the port to TCP 80 which is Generic one. works well.

Thanks...
