Guys i have a solution.
I read that swarmagent is use port 8008 to communication. I checked via cmd (netstat -p utp -t -p -b) and i realized that one of my remote management program is listening the 8008 port. After i uninstalled this program the agent is working very well…
So there is another question: Is there any way to force swarmagent to communicate another port?
