www prefix doesn’t work with https

[ZevEisenberg]

I think @chrisballinger and I have identified an issue with HTTPS and subdomain redirects:

http://wtfautolayout.com ✅ (redirects to www) http://www.wtfautolayout.com ✅ https://wtfautolayout.com ❌ (hangs) https://www.wtfautolayout.com ✅

Thanks very much for spotting this, I'll have a look into it.

I think this is a limitation of my current setup, where redirection from wtfautolayout.com to www.wtfautolayout.com is configured in the DNS provider (Namecheap), and SSL certs are managed via Heroku's Automated Certificate Management.

Heroku documents the issue here, and recommends using ANAME/ALIAS records for the redirection, but Namecheap doesn't support such records. I think I'd need to move DNS provider and manage redirection at the app level instead to resolve the issue, but I'm not sure it would be worth the complication.

Perhaps there's another solution though, as I'm not knowledgeable in this area.

You can use free tier Cloudflare DNS for CNAME flattening and "Universal SSL": https://support.cloudflare.com/hc/en-us/articles/204144518-SSL-FAQ

@chrisballinger Thanks so much, that looks like a much simpler solution.

This has now been set up, and https://wtfautolayout.com should now redirect properly (thanks @akramhussein for your help). It's brought a number of other improvements too so thanks for raising this issue.
