I am new in UR robot. I have a problem with connecting via IP to the UR. It is a UR series-10. sometimes it works but sometime I don’t have any connection with my UR. These are my network settings:
and I get timed out! message.
So taking a quick look, it looks like you’re not using a router. Neither a DNS server in this case (as far as I know - I’m no network expert). 
Remove the DNS IPs from the robot as well as the gateway. Your PC will then have 192.168.5.1 as IP and your robot 192.168.5.5.
I found the issue. It was due to incomplete run of the python program, so the laptop-robot connection route remained busy.
