Hi, I'm a freshman for ROS. Here I meet a problem as shown in the title:

ERROR: Unable to communicate with service [/clear], address [rosrpc://xxx-GP62MVR-6RF:36963]

when I type the "rosservice type /clear" in the terminal under "ubuntu".

Can anyone help me to solve the problem? Thanks.

Hi, I also experienced this error before. shutdown all the nodes and roscore with Ctrl-C, and then restart roscore should resolve this issue. -jc
