I have a question about TSparkle and TXDataServer and a windows service. Today the service got an error
"SPARKLE -> Exception on process requesting. EHttpApiException: HTTP Server API Error. An operation was attempted on a nonexistent network connection"
the JSON we received when the error occurred was big.
When I used postman on my machine to process the JSON it did take about 1.5 min to give an reply.
What is the reason for this error and what can I do to fix the error

The error happens when the server tries to send a response but the client is gone.

Indeed, it's likely to happen in endpoints that took too long to process, when the request processing is finished and the server tries to send the response back to the client, there is no client anymore because it got tired of waiting (timeout).

You can safely simply ignore such errors.
