hi @tooold Can you add a call to your startup function
printDNS();
And add this function to your program
void printDNS() {
IPAddress dnshost(ip_config.aucDNSServer[3], ip_config.aucDNSServer[2], ip_config.aucDNSServer[1], ip_config.aucDNSServer[0]);
Serial.print("DNS IP : ");
Serial.println(dnshost);
}
Some cores develop DNS problems, if it displays DNS IP: 76.83.0.0
then we have a DNS lookup problem. You can read this thread for more info -
Let me know what you discover
