Not able to access RMF-dashboard from remote pc

[Anisha-thakkar6]

I have tried running rmf_demos from the given branch https://github.com/open-rmf/rmf_demos/tree/humble,
and I am trying to visualize through rmf-web with humble branch https://github.com/open-rmf/rmf-web/tree/humble
System info:
Ubuntu 22.04.05 LTS
ROS2 Humble
rmf_demos- Humble branch
rmf_web- Humble branch

Issue:
While accessing rmf_web (dashboard) through the localhost it works well, map and robot status all info are visible but when trying access from remote pc in the same network as host pc in which demo and rmf-web enviornment is running.

For accessing rmf_dashboard through different pc I have changed in .env file from localhost (127.0.0.1) to 0.0.0.0 and I am running the demo on my LAN ip.
While I try to access from the remote pc browser it connects, it loads the rmf_dashboard but it doesn't load the data (either map or tasks) and throws javascript network connection error as mentioned below.

Any suggestions or solutions will be very helpful.

I believe this is due to the URL of the API server still configured as localhost. You can confirm this by checking the network tab in inspect of your browser (remote PC) when it is rendering the dashboard. Verify the server URLs that the dashboard is trying to request from. If it is localhost, this means that your remote PC's browser is trying access an instance of the API server locally on the remote PC.

Barring any weird networking or firewall related issues, as long as you point it to the accurate IP address and port number of the API server running on your LAN, the remote dashboard should be able to perform requests successfully

Thank you for the guidance. I resolved the issue there were still some changes left in the config files, I completed those and successfully able to visualize rmf dashboard on the remote server but there is still one problem I am facing.
I am successfully able to visualize map, task data and door data but robot data is missing in local host and remote host too. I tried to debug but couldn't find the cause behind it. If you can help what might be causes, It would be helpful.

@Anisha-thakkar6 robot data is published using websockets, make sure that you have the server_uri set up when launching the fleet adapters. Please follow the instructions from https://github.com/open-rmf/rmf_demos?tab=readme-ov-file#rmf-web-quick-start closely
