Unable to create a WebSocket connection

[ivanayov]

Hello,

I'm running skydive with NSM, as usual, using the same config and same image, but this time the network topology is not visualized and the agent log has this error message:

2020-04-03T10:39:17.258Z        ESC[34mINFOESC[0m       websocket/client.go:511 (*Client).Connect       nsm-worker2: Connecting to ws://0.0.0.0:8082/ws/agent/topology
2020-04-03T10:39:17.259Z        ESC[31mERRORESC[0m      websocket/client.go:568 (*Client).Start.func1   nsm-worker2: Unable to create a WebSocket connection ws://0.0.0.0:8082/ws/agent/topology : dial tcp 0.0.0.0:8082: connect: connection refused

Has anyone encountered such a problem before?

Thanks

@ivanayov It seems that the analyzer the agent is trying to connect to, is not running. What are you using to deploy Skydive ?

@lebauce I'm using the deployment we have in networkservicemesh/skydive including some fixes from here.

The analyzer is running and its logs show no errors. Seems like something happened in the connection between the agent and the analyzer. I didn't do any changes since this deployment/image were working well. It might be a fully local problem as well.
