Messages being blocked from publishing

I am running 2 nodes. One is polar_scan_matcher and the other one is my own node that publishes scan messages. Something is wrong somewhere because when the 2 nodes run at the same time, the publisher of the scan messages is being block as I received an error saying "WARNING: no messages received and simulated time is active. Is /clock being published?" when I run "rostopic echo -c /scan"

As I run "rostopic list", I got these topics:/clock, /goal, /imu, /initialpose, /pose,/pose2D,/rosout, /rosout_agg,/scan,/tf.

What could be the possible culprit? How do I fix it?
