Problem Description

When requests running with delay several seconds between on core 2.5.2 the data (received with .getString()) not modifying (with reuse set to true).
When I set reuse false - response just get w/o body. And every second response return -2 HTTP error code. In both situations script on server the same (obviously). And this problem doesn't happen on 2.4.2 core.
Here #6149 man stuck with the same problem, but no one respond.

I also tested with https.useHTTP10(false), this also had no affect.
And I tried use latest version from git - same problem.

[dzmpr]

So, anyone can tell me about this situation? Is it known bug which will be fixed in next updates, or no one really knows about this?

@dmdt are you able to try PR #6176 ?

[dzmpr]

@d-a-v Tried, this has no affect on behaviour.

hello there, am also having same issues, am trying to post data to my https://server online and am getting response code: 200 but the payload returns :datanotposted from the server

[dorindabassey]

`// FROM HERE!!!
if (WiFi.status() == WL_CONNECTED) {
HTTPClient http;

// Your Domain name with URL path or IP address with path
// http.begin(serverName);

// Specify content-type header

// Prepare your HTTP POST request data
String httpRequestData = "api_key=" + apiKeyValue + "&name=" + incomingName + "&email=" + incomingEmail + "&userid=" + userId + "&useramount=" + userAmount + "";

Serial.println(httpRequestData);

Serial.println(httpsbegincode);

// Send HTTP POST request
int httpResponseCode = http.POST(httpRequestData);
String payload = http.getString();
Serial.println("PAYLOAD");
Serial.println(payload);


if (httpResponseCode > 0) {
  Serial.print("HTTP Response code: ");
  Serial.println(httpResponseCode);
}
else {
  Serial.print("Error code: ");
  Serial.println(httpResponseCode);
}
// Free resources''

http.end();
Serial.println("connection over");

}
else {
Serial.println("WiFi Disconnected");
}
