使用ZentriOS hup命令通过AWS API Gateway上传文本文件遇TLS握手错误

Hey there, let's work through this TLS handshake error you're facing when using ZentriOS's hup command to upload text files to AWS API Gateway. Error code 5018 (0x28) in ZentriOS usually ties to TLS protocol mismatches, certificate validation issues, or missing Server Name Indication (SNI) support—all common hurdles when connecting to AWS services.

Here are actionable steps to fix this:

• Ensure you're using TLS 1.2 or newer
  AWS API Gateway no longer supports outdated TLS versions like 1.0/1.1. Check your device's current TLS setting with:

  get tls.version
  

  If it returns anything other than 1.2, update it and reboot:

  set tls.version 1.2
  reboot
  

• Validate your CA certificate bundle
  AWS API Gateway's certificates are signed by trusted root CAs, so your ZentriOS device needs the correct root certs to verify the connection. Check your current CA cert configuration:

  get tls.ca_cert
  

  If it's empty or pointing to an outdated bundle, upload the Amazon Root CA 1 (matching your API Gateway's region) to your device's file system, then set it with:

  set tls.ca_cert /path/to/AmazonRootCA1.pem
  save
  reboot
  

• Enable Server Name Indication (SNI)
  AWS API Gateway uses virtual hosting, which requires SNI to route requests correctly. Check if SNI is enabled:

  get tls.sni
  

  If it returns 0 (disabled), turn it on and save changes:

  set tls.sni 1
  save
  reboot
  

• Double-check your API Gateway URL
  Confirm your target URL is a valid HTTPS endpoint (AWS doesn't support HTTP for API Gateway) with no typos. A correct URL looks like:
  https://{api-id}.execute-api.{region}.amazonaws.com/{stage}

• Rule out network restrictions
  If your device is behind a firewall or proxy, ensure port 443 (HTTPS) isn't blocked. Test the API Gateway URL from the same network using curl to confirm you can establish a TLS connection outside of ZentriOS.

If these steps don't resolve the issue, pull up ZentriOS system logs with log read—this will show exactly which part of the TLS handshake is failing (e.g., certificate rejection, protocol mismatch) for deeper debugging.
