Hello, I'm trying to setup ROS noetic on multiple machines on the same network. I've followed the network setup tutorial (http://wiki.ros.org/ROS/NetworkSetup) and the multiple machines tutorial (http://wiki.ros.org/ROS/Tutorials/Mul...), and everything works fine. I setup the ROS_MASTER_URI and ROS_HOSTNAME on both machines, and I can run the talker on one machine and run the subscriber on the other machine, with no problem, However, if I try to launch roswtf in the machine where the master is not running I receive the following error:

Found 2 error(s).

ERROR Could not contact the following nodes:
 * /rosout

ERROR Errors connecting to the following services:
 * service [/rosout/get_loggers] appears to be malfunctioning: Unable to communicate with service [/rosout/get_loggers], address [rosrpc://otto-nuc:56757]
 * service [/rosout/set_logger_level] appears to be malfunctioning: Unable to communicate with service [/rosout/set_logger_level], address [rosrpc://otto-nuc:56757]

Do you have an idea why can I subscribe correctly to the topics such as the talker example, but I cannot connect to the rosout node or call the rosout services?
