This happened earlier this week as well and resolved on its own, now it's back!

Custom domain lenguazen.com is failing at TLS handshake. The Railway-provided .up.railway.app URL works fine.

- DNS resolves correctly to 66.241.124.147 (Railway IP)

- TCP connection on port 443 succeeds

- SSL handshake fails: SSL_connect: SSL_ERROR_SYSCALL in connection to lenguazen.com:443

- No HTTP response is ever received

Steps to reproduce:

curl -v https://lenguazen.com/

Expected: Valid TLS handshake + site loads

Actual: SSL_ERROR_SYSCALL during handshake, connection drops

Environment:

- Railway app is running and accessible via .up.railway.app URL

- Custom domain DNS is pointing to Railway (66.241.124.147)

- No recent changes to domain or DNS config

Likely the SSL cert for the custom domain expired or failed to renew.
