Heroku绑定GoDaddy域名失效，需将域名转发至Heroku博客站点

Hey Ed, let's break down how to get your domains efkhunt.com and www.efkhunt.com properly pointing to your Heroku blog, and resolve that SSL error once and for all—since you're willing to upgrade to the Hobby Plan, that's the key to fixing the SSL side of things.

1. Fix the Root Domain (efkhunt.com) Redirect Problem #

Right now, your A record for the root domain is pointing to a static Heroku IP, which causes the unwanted redirect to classical-orangutan-xxxxxxxxxxxxxx.herokudns.com. Heroku uses dynamic IPs, so A records aren't reliable here. Here's how to fix it:

• First, head to your Heroku app dashboard → Settings → Domains and certificates, click Add domain, and enter efkhunt.com. Heroku will generate a target domain (looks like xxxx.herokudns.com)—copy this value.
• Go back to your GoDaddy DNS settings, delete the existing A record for @.
• Add a new CNAME record:
  • Name: @
  • Value: The xxxx.herokudns.com domain Heroku gave you for efkhunt.com
  • TTL: Keep it at 600 seconds
• This uses GoDaddy's CNAME flattening feature to make the root domain behave like a CNAME, which is the supported way to point root domains to Heroku.

2. Resolve the www.efkhunt.com SSL Error #

The ERR_SSL_PROTOCOL_ERROR happens because Heroku's free tier doesn't support custom SSL certificates—upgrading to the Hobby Plan fixes this, and lets you use Heroku's automated SSL management. Here's the process:

• First, upgrade your Heroku app to the Hobby Plan: In your app dashboard → Settings → Plan, select Hobby and complete the payment setup.
• Back in Domains and certificates, click Add domain again and enter www.efkhunt.com. Heroku will generate another xxxx.herokudns.com target domain—copy this.
• In GoDaddy's DNS settings, update your existing www CNAME record to use this new Heroku-generated value (replace the current thermal-centipede-xxxxx.herokudns.com if it doesn't match).
• Now, enable Automated Certificate Management (ACM) in Heroku: Under Domains and certificates, click Configure SSL, select Automated Certificate Management, and follow the prompts. Heroku will automatically issue a free Let's Encrypt certificate for both your domains, which renews automatically.

3. Verify Your Final DNS Settings #

After making these changes, your GoDaddy DNS records should look like this (ignore the _domainconnect, NS, and SOA records—those are fine to keep):

• CNAME @ → [Heroku's root domain target]
• CNAME www → [Heroku's www domain target]

You can verify the DNS propagation by running these commands in your terminal:

nslookup efkhunt.com
nslookup www.efkhunt.com

Wait 10-15 minutes for any remaining DNS cache to clear, then test both domains in your browser—they should now redirect properly to https://efkhunt.herokuapp.com/ without SSL errors.
