For running validate nodes, through set up, now i can see my node on the telemetry. but I don't know how to connect to polkadot.js.

polka wiki says

"You can generate your Session keys in the client via the apps RPC. If you are doing this, make sure that you have the PolkadotJS-Apps explorer attached to your validator node"

But I don't get it. How do I generate session keys? I use ssh though google cloud, do I have to do something in ssh? What code is to get the session keys and how my node can attach my poladotjs-app?

I think my main question is "how can I find custom endpoint(node`s address, wss) from the google cloud (SHH, code, or etc)?"

The polkadot wiki is your friend, if you look on the same page a little lower you see the cli instructions (cli=command line interface=what you need when using ssh).

Using polkadot.js is a lot more difficult because you need to set it up on your server of create a ssl proxy when using the public version.

In short you need to run the following command in a shell on your server: echo '{"id":1,"jsonrpc":"2.0","method":"author_rotateKeys","params":[]}' | websocat -n1 -B 99999999 ws://

The port (9944) can be different depending in your startup command.
