The problem was a networking error with the LiDAR and the PC. The IP Address was slightly off and was found by using SOPAS to set the IP Address as the same as the computer and adjusting the last digit in the IP Address to a different value.

PC IP: 169.254.149.???

LiDAR IP: 169.254.149.XXX

After this, the error on the ubuntu side was that the wired connection was not connecting appropriately due to the IP error. It was also not staying connected so I then used the network manager to change IPv4 to a link-Local Only to allow for the connection to be secured. Now the node sick_tim_5xx.launch was able to be executed with no errors
