Heroku custom domain ssl name mismatch error

I've added a custom domain (bought on GoDaddy) to my Heroku app and am on the hobby dyno. When I type in www.example.com everything works fine, but when I open example.com I get a name mismatch error.

My cname host www points to example-78914389.herokudns.com and I have forward to https://www.example.com on GoDaddy enabled.

The certificate is only valid for the following names: shortener.secureserver.net, www.shortener.secureserver.net.

Why is the certificate valid for these domains and not for my example.com? I don't know if it matters, but I just ported the domain from zeit now to GoDaddy.

I presume you're using GoDaddy's redirect to send example.com to www.example.com. If so, that service doesn't support HTTPS. Most registrar redirect systems don't; CloudFlare and Google Domains are some of the only ones I've found that do. - ceejayoz
@ceejayoz I'm using the Forward to function in GoDaddy. Does that mean I can't get it to work at all? - Jona
Correct, at least with GoDaddy. That said, most people won't type the HTTPS in at all. - ceejayoz
I'm not sure but it looks like it works now. I had set cname TTL to 600 seconds a half hour ago and when I use a private window now it does work. - Jona
You're saying https://example.com/ works, with the S and no-www? Doesn't match my experience with GoDaddy, but perhaps they finally fixed it. - ceejayoz

Problem solved! I transferred my domain from GoDaddy to namecheap, then made an ALIAS record. I've also added example.com to my app in Heroku. I now have www.example.com and example.com added and both domains work.
