> NetworkInfo from the agent /state endpoint is not correct, which is also
> different from the networkInfo of /containers endpoint. Some frameworks rely
> on the state endpoint to get the ip address for other containers to run.

> The ip addresses are different^^.
> The container is in RUNNING state and is running correctly. Just the state
> endpoint is not correct. One thing to notice is that the state endpoint used
> to show the correct IP. After there was an agent restart and master leader
> re-election, the IP address in the state endpoint was changed.
> Here is the checkpoint CNI network information
