Gazebo simulator does not respond to command sent by mavproxy but SITL does

ArduCopter Copter Simulation

I followed the steps here to install Gazebo-ardupilot plugin.
When I launch SITL and Gazebo as mentioned in the documentation, Gazebo does not respond to the command sent to SITL.

In SITL command line, the Gazebo class is compiled and loaded:

[391/502] Compiling libraries/SITL/SIM_Gazebo.cpp
SIM_VEHICLE: Using defaults from (/home/soubhi/Desktop/ardupilot/Tools/autotest/default_params/copter.parm,/home/soubhi/Desktop/ardupilot/Tools/autotest/default_params/gazebo-iris.parm)

The output from Gazebo command line:
Msg] Waiting for master.

I even tried to open port 11345 in mavproxy:
mavproxy.py --master=127.0.1:14550 --sitl 127.0.0.1:5501 --out 127.0.0.1:11345

Operating system: fedora
Gazebo version: 7
SITL Ardupilot is latest one

I will appreciate any help!

Hi @Subhi did you run this command gazebo --verbose worlds/iris_irlock_demo.world after copying your worlds from ardupilot_gazebo/gazebo_worlds to /usr/share/gazebo-7/worlds/?

Also, you can try copying ardupilot_gazebo/gazebo_models to ~/.gazebo/models

Finally it worked after many hours. I do not know what was the problem but after restarting the computer it starts working. Thank you!
