Foxglove Websocket IPv6 Support

[joewong00]

Hi

I'm currently using foxglove studio to view my ROS data and it works well. However I would like to know if foxglove websocket supports IPv6 instead of IPv4. For example, I would like to connect to the ROS master using IPv6 address through websocket connection so that it can be viewed in the browser. The format would be as follow:

ws://[ipv6-address]:8765

I have tried this but it does not work. Is it because that foxglove websocket is not yet supporting IPv6? May I know will there be any fix for this?

Thanks.

Can you please explain what you mean by “does not work”?

Hi,

It says connection failed, I have already launched the foxglove bridge in the ROS master machine. The error message is to check that websocket server at ws://[ipv6_address]:8765 is reachable and supports protocol version foxglove.websocket.v1

Is the computer where you are running Studio otherwise able to reach that address?

Yes, I am able to ping to that address. I can also connect to it using the tornado websockets to visualize streaming data from the ROS master.

Are you able to use IPv6 to connect to a websocket server on your local machine?

I just tried with:

npx @foxglove/ws-protocol-examples@latest image-server

and was able to connect to ws://[::1]:8765.

How are you connecting using tornado websockets?

Hi, I tried running on local machine, and the connection fails as well. Using ws://[::1]:8765.

This sounds like a configuration issue if your computer is not able to make any ipv6 connections. You'll probably need to search online for advice based on your specific OS, hardware, and network setup.

I faced the same issue with IPv6 address. But it got solved by setting the address param to address:="'::'"

I faced the same issue with the IPv6 address. But it got solved by setting the address param to address:="'::'"

for example: ros2 launch foxglove_bridge foxglove_bridge_launch.xml address:="'::'"
