Hello, I followed this tutorial to set up a discovery server for ros2. The talker and listener examples all worked fine.

However, when it came to

ros2 topic list
ros2 node list
which were not part of the tutorial exactly, I did not find any nodes or topics. I exported the Server as follows in every terminal session:


It seems like this is enough for talker and listener nodes to find each other, but not for ros2 command line tools. Also, rqt did not show any nodes or topics either. Command line tools and rqt work fine with standard discovery.

Is there anything else I need to do for ros2 topic list to show the /chatter topic?
