Seems to be an issue with the cert:

curl: (35) OpenSSL SSL_connect: SSL_ERROR_SYSCALL in connection to yml.publiccode.tools:443

@ericherman it should be back for everyone now. Thanks again for the notification 🙌

Thanks @ruphy for the fix.

Keeping this open as a placeholder, we need a clear and streamlined process so this doesn't happen again
