[JENKINS-71986] Jenkins agent log has only a spinning wheel and agent can not connect to the controller

[jenkins-infra-bot]

I have noticed that when I click relaunch the agent button but it is not connecting. And when I look up the agent log, there is nothing but a spinning wheel. It still shows only a spinning wheel no matter how many times I click the button. What I have to do is to configure the agent and actually change nothing then click save and relaunch the agent. I think reboot the agent and try to connect it will produce this issue.
