Custom Domain - www improperly configured

[TMB-Business]

My custom domain is working, but www is not propagating. Any ideas on what I'm doing wrong?

For GitHub Pages, you usually need two DNS records:

1. An A record pointing @ to GitHub's pages IPs (185.199.108.153, 185.199.109.153, etc.)
2. A CNAME record for www pointing to yourusername.github.io

If your apex domain (example.com) works but www doesn't, the most common issue is that the www CNAME is missing or pointing to the wrong place.

Check your DNS settings and make sure:

• www CNAME -> yourusername.github.io
• Or if you're using an ALIAS/ANAME record at the apex, double check it's set up right

Also check in your repo Settings > Pages that you've entered both domains (or just the apex and check the "Enforce HTTPS" box). Give DNS up to 10 mins to propagate after changing it.

Thank you. I think there were three issues happening. 1. I didn't have https checked. 2. The domain host site was having technical issues and wouldn't save the CNAME record. 3. Maybe the CNAME record name is case sensitive. When I changed it to all lowercase, github was able to propagate it. * Clarity is the enemy of all enthusiasm. - Burke *
