1. Server Closes Connection Prematurely
The server might be closing the connection before all the intended data has been sent, perhaps due to a timeout or misconfiguration on the server side. This would lead to the client expecting more data than it actually receives.
Suggestion: If possible, investigate the server configuration or contact the server administrator to ensure it's configured to handle long-running requests appropriately.
2. Network Interruptions or Proxy Issues
Network issues or proxies between your client and the server might be interfering with the connection, especially for long-running requests.
Suggestion: Test the request from a different network or machine, if possible, to rule out local network or proxy issues.
3. MATLAB HTTP Options Configuration
Although you've set a lot of the relevant timeouts to Inf, ensuring no timeouts on MATLAB's side, there might be other configurations or limits in the MATLAB HTTP engine or the underlying system that are causing the issue.
4. Workaround: Retry Mechanism
If the data you're expecting can be requested in smaller parts or if the service supports range requests, implementing a retry mechanism or pagination in your request logic could be a workaround. This would involve breaking down the long-running request into shorter, more manageable requests.
5. Increase Server Send Buffer
On some occasions, the server's send buffer size might be insufficient for large responses or slow connections, causing the server to close the connection if the buffer overflows.
Suggestion: Check if the server allows configuration of the send buffer size and increase it if possible.6. Debugging with External Tools
To further diagnose the issue, you could use external tools like Wireshark or Postman to mimic the requests and observe the behavior. These tools might give you additional insights into whether the issue is with the specific way MATLAB handles the requests or a more general server-side issue.
Suggestion: Mimic the request using Postman or cURL and observe if the issue persists. If it doesn't, the problem might be specific to how MATLAB handles the request or interprets the response.
If none of these suggestions resolves the issue, the best course of action would be to reach out to MATLAB support for assistance. They might be able to provide more specific advice or identify if there's a bug in the MATLAB HTTP client handling.
