Arduino Uno /w w5100 shield not connecting to local server

@wolph42, are you trying to use Blynk.begin() along with Blynk.config() and Blynk.connect() ?? If so, it is not a correct approach. I think you just forgot, that Blynk.begin() is a “combo” command and those latter are not necessary. You were active on this (below) topic too, so just a reminder:

Check connection status in loop and reconect

remove the Blynk.begin() and try: byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED }; //you can edit it to your needs if (Ethernet.begin(mac) == 0) { Serial.println("Failed to configure Ethernet using DHCP"); } else Blynk.config(auth); Blynk.connect(); } The rest should be fine as is What error?
