longhorn/longhorn#2118 (comment)
The longhorn-ui uses websockets to communicate with the backend, the icons on the bottom right are the statuses of the websocket connections. Can you generate a support bundle manually, below are instructions to do this via curl please replace the longhorn-backend.xip.io with your own exposed service.
The easiest is to expose longhorn backend service, as shown below:
// requesting support bundle via post
curl -i -X POST -H 'Content-Type: application/json' -d '{ "issueURL": "https://github.com/longhorn/longhorn/issues/2118", "description": "2118" }' http://longhorn-backend.xip.io/v1/supportbundles
