I am using ROS Noetic in Ubuntu 20.04. I followed each and every step given in robotis e-manual. However, when I run the following command

roslaunch turtlebot3_bringup turtlebot3_robot.launch

I receive the following message:

RLException: ERROR: unable to contact ROS master at [http://192.168.0.123:11311] The traceback for the exception was written to the log file

I have checked the connections, the IP addresses, the bashrc files of both the robot and the remote PC. I have redone the entire setup process for at least 6 times as of now but no solution has been found.

Kindly help me.

I checked the ROS_Master URI in the turtlebot3 and also the Host IP. Still, the same issue.

I will check the /etc/hosts and get back to you
