Newbie, seems I can't get certs right for SSL/TSL

Using Jenkins Ask a question

Here’s my error while Docker builds a Jenkins instance: ‘PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target’

When I look at Jenkins (localhost:8080) the container is running but it thinks I’m offline, so I can’t access plugins needed for further work. I saw a question from Oct 2023 that seems similar but I’m not trying to connect Jira to Jenkins, just connect my container so I can get plugins and I don’t have Java installed (as far as I know).

I’m not fluent in Docker and a total newbie on Jenkins.

MY SETUP:
macOS Sonoma 14.5 with M3 Max processor
Docker version: 4.29.0
Jenkins version: Docker Hub jenkins/jenkins (pulled 5/23/2024) with no added plugins

Docker compose.yaml:

services:
  jenkins:
    container_name: jenkins
    image: jenkins/jenkins
    ports:
	- "8080:8080"
    volumes: 
	- "$PWD/jenkins_home:/var/jenkins_home"
    networks:
