Having issues with muling

[coopbank2 17]

Hi,

I am using a script that has built in muling. The script is "Nano Miner" but I do NOT think something is wrong with the script. I think the fault is somewhere else. Anyways, the issue is that I start the script on my Master, then I start the script on my slaves. Everything works 100% flawlessly. However, if I create a new computer (all same network, firewall OFF, no VPN) and then create more slaves and specify that the master is located on <local_ip_address>, then the new slaves fail to connect to the master! In other words, master + slaves all running on localhost is working GREAT, but if I have a second machine with more slaves and specify the master computer IP-address instead of "localhost", then it fails to connect to master.

My english is not too good, so to demonstrate one more time:

The computers can PING eachother no problem, but for troubleshootings sake I even turned off firewall on both computers. I have tried 2 different routers.

Does anyone know what could be wrong? Right now I am solving this by running 1 master account on each computer, but this feels like a half-assed workaround that I personally want to get rid of ASAP. Kind regards.
