What did you do?

I accessed the default dashboard in pd, and expose it to public network by ingress, and when I access it will redirect me to http://{name of cluster}-pd-0.{name of cluster}-pd-peer.tikv.svc:2379/dashboard/ I cannot find any way to resolve this problem so I try use independent dashboard.

And It shows

I opened developer tools in chrome.

    // (Deprecated) EnableDashboardInternalProxy would directly set `internal-proxy` in the `PdConfig`.
    // Note that this is deprecated, we should just set `dashboard.internal-proxy` in `pd.config`.
    // +optional

I saw it Deprecated, why?
