I try to use laser scan of hokuyo lidar uam-05lp-t301 but it say I could not open ethernet port

192.168.1.10:10940 could not open ethernet port.

then I try to ping 192.168.1.10 make a check that this ip address is available

ping 192.168.1.10 PING 192.168.1.10 (192.168.1.10) 56(84) bytes of data.

I'm having the same problem with Hokuyo ust-20lx with ros2 on container. Inside the container, using the host network mode. I can ping the laser from inside the container but node do not seems to work
