I invoke the pipeline editor, it prompts me with the message "You need to register this public SSH key with your Git server to continue"

Bosses, Help needed.

When I create a new pipeline using the Blue Ocean plugin, even after I have properly configured the key pair and set up password-free login, as soon as I invoke the pipeline editor, it prompts me with the message “You need to register this public SSH key with your Git server to continue”.

This video can reproduce the problems I encountered.
