[ranjeetthorat]

Question 💬

I am using next-auth with okta providers . I am able to to get okta login page when i click on sign in button in devlopment and local production builds. But when deploy it to using docker on my server I get 404 error . Console has "CLIENT_FETCH_ERROR" error.
I have set NEXTAUTH url in nex.config.js

How to reproduce ☕️

/** @type {import('next').NextConfig} */
module.exports = {
  env: {

    NEXTAUTH_URL: 'https://mydomain-internal.example.com'
  },

this is [...nextauth].ts

providers: [
    Providers.Okta( {
      id: 'okta',
      name: 'Okta2',
      type: "oauth",
      version: "2.0",
      clientId: 'mysecret',
      domain: 'xyz.domain.com/oauth2',
      protection: 'pkce',
    } ),
  ],
