Under HA sync failed with error:

"Unable to Authenticate with Primary, rpcnode password might have changed please reset it and try"

When resetting it on Primary it  times out.

1. Check whether SSL feature is enabled on both devices.
2. Check whether ns-server-certificate (default cert) is preset on both the device.
3. Check whether the internal services are UP on both the devices.
4. If all 3 are done RPC node password should get reset smoothly.
