WebSocket opening handshake timeout

[prashanth2692]

Hello,

I have been trying to use ROSIntegration plugin on Windows. I have followed instructions to publish to a topic. The connection is being established but the messages doesn't seem to ROS network.

Command used to launch rosbridge:
roslaunch rosbridge_server rosbridge_tcp.launch bson_only_mode:=True

output

started roslaunch server http://127.0.0.1:58043/
