The certificate error is happening because you still haven't added apps to your site.
With no apps on the site, there's no site.
Since there's no site, the requests are reaching our server and getting the default server certificate.
To fix this:
- Go to https://my.opalstack.com/routes/
- Click the Edit icon for your indianocean.dev site.
- Under "Application Routing Info" add your application to the site.
- Click the Save button at the bottom of the page.
- Wait 2-5 minutes for the change to take effect.
