Error "This site can’t be reached" when upgrading jenkins to version 2.401.3

Hi everybody,

I got error “This site can’t be reached” after upgrading jenkins

I looked at the log in file jenkins.err and found that it seems to be caused by I used jdk 8.

2023-08-17 08:05:13.969+0000 [id=22105] INFO hudson.lifecycle.Lifecycle#onStatusUpdate: Jenkins stopped
Running with Java 8 from C:\Program Files (x86)\Jenkins\jre, which is older than the minimum required version (Java 11).
Supported Java versions are: [11, 17]
See https://jenkins.io/redirect/java-support/ for more information.

But the current java environment I am using is 11.0.17 which is suitable for the requirements of version 2.401.3

I’m not sure if it’s jenkins using old jdk, or is it some other reason.
Jenkins was installed by my former colleague, he quit and I continue to maintain it. I’m a newbie so I don’t have much experience, I hope someone can help me fix this error

Thank so much!
