Hi, First of all, thanks for the great library. The library is working very nicely, but i am facing an issue which i do not think is because of this library and i need help/guidance to resolve it. Description: Board: ESP32 cam Example sketch: esp32 cam I have two mobile phone as hot spots with different networks, i connected the same esp32 cam with same sketch to both hot spots with the following results

Hot spot "A" - Did not send or receive message. To check telegram, i sent http request from browser which was also not successful.

Hot spot "B" - Sending and receiving messages successfully. Also checked telegram by sending http request from browser which was also successful.

I spent good amount of time to google and tried few different things and changed the dns settings of Hot spot "A" to private dns (dns.google). Then i was able to send http request to esp32 cam from browser, but example sketch is still not sending or receiving the messages. any help would be much appreciated. Thanks

Hi @navdeepssidhu Sorry fot late reply.

You can set dns settings also for ESP32 board and it should work.

IPAddress local_IP(192.168.xxx.xxx);   // ESP32 IP address
IPAddress gateway(192.168.xxx.xxx);  // Your router IP address
IPAddress subnet(255, 255, 255, 0);
IPAddress primaryDNS(8, 8, 8, 8);   // Public DNS1
IPAddress secondaryDNS(8, 8, 4, 4); // Public DNS2
WiFi.config(local_IP, gateway, subnet, primaryDNS, secondaryDNS)
