Getting SSL error on the custom domain cname url

Posted on August 8, 2024

Hi, I recently deployed an application through the App Platform with a custom domain. I manage my domain through Digital Ocean. I can access the domain directly without any issues, but when I try to access the CNAME, I get an SSL error in the browser. The following is the error I am getting,

# This site can’t provide a secure connection

**www.joshyjoy.com** uses an unsupported protocol.

ERR_SSL_VERSION_OR_CIPHER_MISMATCH

I created the cname as follows

CNAME www.joshyjoy.com  portfolio-ui-vdk7u.ondigitalocean.app.  3600

Even after 1-2 hour, I am facing the same issue.

Hey 👋

This is quite interesting. Before creating the CNAME record, did you also add the domain name to your App Platform as described here:

https://docs.digitalocean.com/products/app-platform/how-to/manage-domains/

Let me know how it goes after adding the domain to the App Platform, and what the domain status is after it has been added.
