So, i am trying to get a esp32cam module to run a web server via a LTE Router with UPnP. I have created a No-Ip Account and a hostname without ddns key for my project. The router has a working sim-card with internet flatrate. The problem is i am not getting a connection to no-ip and i have no idea, why. The code looks like this (UPnP Example):

/
Note: This example includes the library EasyDDNS. You'll have to add this package using your Arduino Library Manager. The purpose of this package is to publish your dynamic IP to a DDNS service that will allocate a human readable address to your current IP. If you do not need that, you can remove this dependency. /

include // see note above

const char ssid = ""; const char password = "";

define LISTEN_PORT 2222 // http://:/?name=

define LEASE_DURATION 36000 // seconds

define FRIENDLY_NAME "" // this name will appear in your router port forwarding section

define DDNS_USERNAME ""

define DDNS_PASSWORD ""

define DDNS_DOMAIN ""

TinyUPnP tinyUPnP(20000); // -1 means blocking, preferably, use a timeout value (ms) WebServer server(LISTEN_PORT);

const int led = 13;

void handleRoot() { digitalWrite(led, 1); server.send(200, "text/plain", "hello from esp32!"); digitalWrite(led, 0); }

void handleNotFound() { digitalWrite(led, 1); String message = "File Not Found\n\n"; message += "URI: "; message += server.uri(); message += "\nMethod: "; message += (server.method() == HTTP_GET) ? "GET" : "POST"; message += "\nArguments: "; message += server.args(); message += "\n"; for (uint8_t i = 0; i < server.args(); i++) { message += " " + server.argName(i) + ": " + server.arg(i) + "\n"; } server.send(404, "text/plain", message); digitalWrite(led, 0); }

void setup(void) { pinMode(led, OUTPUT); digitalWrite(led, 0); Serial.begin(115200); WiFi.mode(WIFI_STA); WiFi.begin(ssid, password); Serial.println("");

// Wait for connection while (WiFi.status() != WL_CONNECTED) { delay(500); Serial.print("."); } Serial.println(""); Serial.print("Connected to "); Serial.println(ssid); Serial.print("IP address: "); Serial.println(WiFi.localIP());

boolean portMappingAdded = false; tinyUPnP.addPortMappingConfig(WiFi.localIP(), LISTEN_PORT, RULE_PROTOCOL_TCP, LEASE_DURATION, FRIENDLY_NAME); while (!portMappingAdded) { portMappingAdded = tinyUPnP.commitPortMappings(); Serial.println("");

if (!portMappingAdded) {
  // for debugging, you can see this in your router too under forwarding or UPnP
  tinyUPnP.printAllPortMappings();
  Serial.println(F("This was printed because adding the required port mapping failed"));
  delay(30000);  // 30 seconds before trying again
}

}

Serial.println("UPnP done");

if (MDNS.begin("esp32")) { Serial.println("MDNS responder started"); }

server.on("/", handleRoot);

server.on("/inline", []() { server.send(200, "text/plain", "this works as well"); });

server.onNotFound(handleNotFound);

server.begin(); Serial.println("HTTP server started");

}

void loop(void) {

EasyDDNS.update(300000);

tinyUPnP.updatePortMappings(600000); // 10 minutes

server.handleClient();

delay(5); }

I was not sure which port to use so i chose 2222 not sure if thats the way to go. As all the DDNS Definitions are not used in the code i copied the code from the EasyDDNS page into my code:

EasyDDNS.service("noip"); EasyDDNS.client("DDNS_DOMAIN", "DDNS_USERNAME", "DDNS_PASSWORD");

The esp boots normally and in the serial monitor the last three lines say "UPnP done, MDNS responder started, HTTP Server started". The UPnP stuff seems to work and i am not really sure what i am doing wrong. Can anyone point me in the right direction? Thanks
