Significant Lag on Last Packet with HTTPClient over HTTP, but Not HTTPS #10598

Default HTTPClient timeut is 5000 ms (5 seconds). NetworkClient &getClient(Drivers::string url) {
client = NetworkClient();
client.setTimeout(100); // 100ms reading timeout
clientSecure = NetworkClientSecure();
clientSecure.setInsecure();
if (url.compare(0, 8, "https://") == 0) { return clientSecure; }
return client;

Unfortunately, the proposed solution did not help. That said, isn’t it a bug that when connecting via HTTP, the stream, after downloading the entire resource, waits for a timeout instead of terminating on its own? It seems it should automatically close after the resource is fully downloaded. Especially since this works perfectly fine over HTTPS |

@rvbc1 - I'll take a deeper look into it. |

Using HTTPClient over HTTP results in a significant delay on the last packet (around 5 seconds), whereas this delay doesn’t occur over HTTPS. In general, HTTPS is also noticeably faster, which is surprising since encryption is expected to add some overhead.
The file being downloaded is the same in both cases, from the same server, and the only difference in the URL is whether it starts with HTTP or HTTPS.
Could someone help me understand if I’m doing something wrong, or if this might be a bug?”
