Hello,

I started a launch file with "roslaunch my_pkg myRobot.launch",

I get the message:" [INFO] [1598439727.662673]: Waiting for service /gazebo/spawnurdfmodel"

If i try to start gazebo with "rosrun gazebo_ros gazebo" i get the error: "[Err] [REST.cc:205] Error in REST request

libcurl: (6) Could not resolve host: api.ignitionfuel.org"

I tried to solve the problem with changing the line "url: https://api.ignitionfuel.org" in the /.ignition/fuel/config.yaml to "url: https://api.ignitionrobotics.org"

Also i tried with deleting the /.ignition/fuel/config.yaml file.

It doesnt function, still.

How can i solve this problem?
