With the server running (gz sim -s shapes.sdf), can you try running the following from the terminal you tried running the GUI?

gz service -s /gazebo/worlds --reqtype gz.msgs.Empty --reptype gz.msgs.StringMsg_V -r 'unused: true' --timeout 2000

You should see:

data: "shapes"

If not, there might be something wrong in your network setup.

matt-mueller-ptc commented 8 months ago

Chiming in to say that I have the same exact error when trying to get started with Gazebo. Working on Apple M2 Pro running Ventura 13.6.1.

@azeey when I try your instructions above, I get Service call timed out in the second terminal. How can I debug the network setup or know what the requirements are?

azeey commented 8 months ago

I don't have much experience with network configuration on macOS, but if you can do it safely, a quick thing to try would be to disable the firewall and see if the issue goes away. In general, UDP multicast has been the main issue of these types of problems, so I recommend following my suggestion here

vladveterok commented 5 months ago

gz service -s /gazebo/worlds --reqtype gz.msgs.Empty --reptype gz.msgs.StringMsg_V -r 'unused: true' --timeout 2000

Hey, gentlemen, I'm running these commands and receiving "data: "shapes", as mentioned in a quoted comment. And yet when I'm running gz sim -v4 -g shapes.sdf or any other .sdf file, I'm having this stack of countless [GUI] [Dbg] [Gui.cc:343] GUI requesting list of world names. The server may be busy downloading resources. Please be patient.. I use MacBook Pro M2 with macOS Sonoma 14.4.1

I'm struggling to find anything while googling. @matt-mueller-ptc did you manage to solve the problem? I appreciate any help.

I have the same message but I using Ubuntu 22.04 only Gazebo11 classic GUI is working neither ignition nor Hurmonic I have deleted everything related to the classic version to see if it is the problem but nothing happend the GUI of the harmonic appear which you can choose whic sdf file you want and when I hit run it fails and print the GUI is not responding and if I run it from the terminal it stays a little bit printing that kind of message wait message then it prints also the GUI is not responding ....... I found someone talking about the firewall and locale setting but nothing , also adding that line to the .bashrc -> export GAZEBO_RESOURCE_PATH=/usr/share/gazebo-harmonic but also nothing happeded do anyone have any idea what is the problem ...

when I run the comand too:

gz service -s /gazebo/worlds --reqtype gz.msgs.Empty --reptype gz.msgs.StringMsg_V -r 'unused: true' --timeout 2000

it prints out service time out

Hi I am also seeing this same issue for Harmonic built from source.

Mechazo11 commented 4 days ago

Hi @rreddy80 I found the solution to this problem as discussed here https://gazebosim.org/docs/latest/troubleshooting/

The following commands should resolve this problem. I tested it in Gazebo Harmonic source built in Ubuntu 22.04

sudo ufw allow in proto udp to 224.0.0.0/4
sudo ufw allow in proto udp from 224.0.0.0/4
gz sim -v 4 empty.sdf

Hey @Mechazo11 That works for me as well, thanks! (Gazebo Ionic on Ubuntu 24.04)

So to me it looks like a problem caused by the firewall configs on one's local host, rather than an incompatibility among the versions or the OS or drivers etc..

Recommend to try this if any others ran into the same problem.

gazebosim / gz-sim
