Remote roscore not working
Hello!
I installed ROS on an MS Azure virtual machine. The communcation between nodes is working when I'm sending data from the cloud to my local machine, but not in the other direction. When publishing from my local PC I see the topic on the machine running roscore, but when I try to echo it, no data is displayed. Do you have any suggestions how can I fix this problem?
Thank you for your answer!

Sounds like your network setup is not quite correct. Make sure you have set ROS_MASTER_URI and either ROS_IP or ROS_HOSTNAME. From the description of your problem (communication in one direction only) it sounds like you have not done the latter correctly. See EnvironmentVariables.

+1: most likely a firewall or dns issue.
