SSH and HTTPS Keys don't work for my Eclipse when trying to connect to GitHub

I'm trying to connect my Eclipse with GitHub by SSH.

In Eclipse, I've generated an RSA key, saved it, and apply.
I also added the SSH to my Github account.

But I still got the following:

Nor would HTTPS work.I tried it. It failed, suggesting that I should set http.sslVerify=false.
I did it, but it didn't help, and I still got this suggestion.

I'm using Eclipse IDE 2021-09, and have updated the Git plugin.
