BasicHttpsClient not working in WIFI_MODE_APSTA

[Zzo911]

Board

Lilygo TG4 (ESP32 WROVER + SIM7600E)

Device Description

Using ESP32 Core 2.0.1 and ESP32 WROVER Kit (all versions)

Hardware Configuration

None

Version

v2.0.1

IDE Name

Ardiono 1.8.18

Operating System

macOS 12.1

Flash frequency

40Mhz

PSRAM enabled

no

Upload speed

115200

Description

When the Wifi is set to WIFI_MODE_APSTA, the BasicHttpsClient is returning an error -1 : connection refused.
The sketch only works in WIFI_MODE_STA.
How is it possible to force the WiFiClientSecure to use the STA instead of the AP interface?

Sketch

void sendPushover(String pushTitle, String pushMessage, uint8_t pushPriority) {
  if (WiFi.status() == WL_CONNECTED) {
    WiFiClientSecure *client = new WiFiClientSecure;
    if (client) {
      client -> setInsecure();
      HTTPClient https;
      if (https.begin(*client, pushServer)) {
        Serial.println("Connection to pushover OK");
        https.addHeader("Content-Type", "application/json");
        String httpsRequestData = "{\"token\":\"" + pushToken + \
                                  "\",\"user\":\"" + pushUser + \
                                  "\",\"title\":\"" + pushTitle + \
                                  "\",\"message\":\"" + pushMessage + \
                                  "\",\"priority\":\"" + pushPriority + "\"}";           
        int httpsResponseCode = https.POST(httpsRequestData);
        if (httpsResponseCode > 0) {
          Serial.printf("Pushover response : %s\n", https.getString().c_str());
        } else {
          Serial.printf("Pushover error : %s\n", https.errorToString(httpsResponseCode).c_str());
        }
        https.end();
      } else {
        Serial.printf("Connection Pushover failed");
      }
      delete client;
    }
  } else {
    Serial.println("Not connected to WiFi, using SIM instead");
  }
}

Debug Message

httpsResponseCode = -1
Pushover response : connection refused

Other Steps to Reproduce

Changing Wifi mode to WIFI_MODE_APSTA

When using WIFI_MODE_STA it's working but I need APSTA as I'm using a portal too :

Hello, can you please retest this on v2.0.3-rc1?

[VojtechBartoska]

I'm closing the issue as expired due to no answer.

If needed, please reopen it.

Thanks for understanding.
