Docker环境下NextJS+NextAuth对接Keycloak认证报错求助

我在Docker环境中使用NextAuth实现NextJS应用与Keycloak的认证对接时，持续出现以下错误：

frontend-1  | [next-auth][error][SIGNIN_OAUTH_ERROR] 
frontend-1  | https://next-auth.js.org/errors#signin_oauth_error connect ECONNREFUSED 127.0.0.1:443 {
frontend-1  |   error: {
frontend-1  |     message: 'connect ECONNREFUSED 127.0.0.1:443',
frontend-1  |     stack: 'Error: connect ECONNREFUSED 127.0.0.1:443\n' +
frontend-1  |       '    at TCPConnectWrap.afterConnect [as oncomplete] (node:net:1494:16)',
frontend-1  |     name: 'Error'
frontend-1  |   },
frontend-1  |   providerId: 'keycloak',
frontend-1  |   message: 'connect ECONNREFUSED 127.0.0.1:443'
frontend-1  | }

该配置在本地非Docker环境下可正常运行，认证能成功跳转到Keycloak登录页面，仅Docker部署时出现此问题。

当前docker-compose.yml配置 #

version: "3.9"

services:
  traefik:
    image: docker.io/traefik
    command:
      - --api.insecure=true

      NEXTAUTH_URL_INTERNAL: http://frontend:3000
      KEYCLOAK_ISSUER: https://auth.example.com/realms/realm-name

  postgres:
    image: docker.io/postgres:alpine
    environment:
      POSTGRES_USER: postgres
      POSTGRES_PASSWORD: postgres
      POSTGRES_DB: db

已尝试的配置调整 #

我也曾尝试将KEYCLOAK_ISSUER改为：

KEYCLOAK_ISSUER: https://keycloak:8080/realms/realm-name

我使用的是NextJS 13版本，非常感谢您的帮助，如果能提供可用示例将不胜感激。
