Hi, we were using App Engine bound to naked custom domain for quite some time. At some moment it just stopped working because of inability to establish SSL/TLS connection.
We have verified domain registered in Google Admin. App Engine is configured to work on this custom domain. SSL Security is set to be Google Managed. DNS records recommended in Control Panel were set correctly. We are completely sure that everything was set up correctly because it was working for several months without a glitch. But recently naked domain stopped working with the following symptoms (replaced my domain with *bla-bla-bla.com*): MacDenisPro3~(:|✔) % curl -vvv https://bla-bla-bla.com * Trying 216.239.34.21... * TCP_NODELAY set * Connected to bla-bla-bla.com (216.239.34.21) port 443 (#0) * ALPN, offering h2 * ALPN, offering http/1.1 * successfully set certificate verify locations: * CAfile: /etc/ssl/cert.pem CApath: none * TLSv1.2 (OUT), TLS handshake, Client hello (1): * LibreSSL SSL_connect: SSL_ERROR_SYSCALL in connection to bla-bla-bla.com: 443 * Closing connection 0 curl: (35) LibreSSL SSL_connect: SSL_ERROR_SYSCALL in connection to bla-bla- bla.com:443 The following command just shows CONNECTED(00000006): openssl s_client -connect itspartner.by:443 -showcerts Interesting that the following commands give *different IPs*: dig www.bla-bla-bla.com @8.8.8.8 dig bla-bla-bla.com @8.8.8.8 I'm really stunned and can't think of a solution other than re-setup everything from scratch. Which will potentially break development process and there's no guarantee that situation resolves itself. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
