What is the issue you’re encountering

I can no longer make a fetch() call from a worker to a public Zero Trust URL of mine, which had been working fine until now.

What steps have you taken to resolve the issue?

I haven’t done anything yet for 2 reasons: 1) It was working fine until today, and 2) The error is telling me to modify a DNS record that Cloudflare automatically generated when I configured the tunnel public hostname.

Was the site working with SSL prior to adding it to Cloudflare?

Yes

What is the current SSL/TLS setting?

Off

Additional info

I realized I had just updated wrangler from 3.100.0 to 3.103.2 when this issue started occurring. I’ve tried every version of wrangler since 3.100.0 with the same result.

When I downgrade to wrangler 3.100.0, it works as expected. I’ve submitted a bug through github.
