Dispatcher Node Unavailable

[ZhongBaode]

Hi, I was facing issue with Dispatcher Node being unavailable, despite reinstalling RMF demo from source or binary.

I had managed to figure out a partial solution and I would like to share this with the community. I am using a laptop which had its network security improved recently, and this was the problem. ufw was enabled and this firewall was blocking the communication for the Dispatcher node. After disabling ufw by using the command "sudo ufw disable", I was able to get the demo's running perfectly again.

However, in the rmf_demo_panel/simple_api_server that states that the default port used was 8083, even after enabling 8083 in ufw settings, I was still unable to get the Dispatcher Node running. If anyone knows what I did wrong here please correct me. In any case, disabling ufw fixed this problem for now.
