GNS3 v1.2.1 IOU could not connect to GNS3 devices

So, I downloaded GNS3 v1.2.1, and loving the new UI. I got my IOU and it is working the way it supposed to work; however, I noticed that I could not connect it to any of GNS3 devices, such as routers, Ethernet switches, etc… As shown in my screenshots below. I was getting an error messages stating Server 192.168.56.101 cannot communicate with server 127.0.0.1, most likely because your local server host binding is set to a local address. Also, unable to use Wireshark on IOU devices between IOUs, the error message Cannot start Wireshark: the /home/gns3/GNS3/projects/gns3 … capture file does not exist on this host.
