HTTPS TLS Handshake Failure on Vercel Hobby Deployment

Hello,

I am experiencing a persistent HTTPS connection issue with my project.

Project: hilalogretmen Domain: hilalogretmen.vercel.app Plan: Hobby (Free)

The domain shows Valid Configuration and Production is selected.

However, the website cannot be accessed. Browsers show ERR_CONNECTION_RESET and curl returns:

curl: (35) Recv failure: Connection was reset

I have tested:

Multiple Vercel IP addresses. Different internet connections, including mobile data. TLS 1.2 explicitly. Google DNS (8.8.8.8). Production Refresh. Domain configuration. DNS resolves successfully, but the TLS handshake fails before any HTTP response is received.

Could someone from the Vercel team investigate whether this is related to Edge routing or TLS certificate provisioning?

I have exhausted the standard troubleshooting steps and need help identifying the server-side cause.

Thank you.

Additional information:

My latest Production deployment status is Ready.

The domain hilalogretmen.vercel.app shows Valid Configuration, and Production is selected.

The HTTPS connection still fails on both Wi-Fi and mobile data with ERR_CONNECTION_RESET.

This appears to be a TLS handshake or Vercel Edge routing issue rather than a build or DNS configuration issue.

Could a Vercel engineer please investigate the Edge TLS response for this hostname?

I also deleted and recreated the domain with the same name, but the issue persists.

Both the main project URL and the deployment-specific URL remain inaccessible.

The deployment status is Ready, and the domain configuration is Valid Configuration.

I have tested on both Wi-Fi and mobile data. The TLS handshake is reset in both cases.

Please investigate this as a possible platform-level connectivity or Edge TLS issue.
