[SOLVED] Devices offline after update blynk local server

Need Help With My Project

Hi Blynkers,
I tried to update my Blynk local server to the last release, but now I have a problem: after the update, my two devices are offline.
I use:

  • Arduino Mega with Ethernet shield
  • Arduino Uno with ESP 8266 shield
  • Blynk Android app v. 2.26.7
  • Local server working before the update “server-0.32.0-java8.jar”, installed on Raspberry PI 3
  • Local server NOT working after the update “server-0.39.4-java8.jar”, installed on Raspberry PI 3

The update procedure that I used is the following:

  • I uploaded the “server-0.39.4-java8.jar” file in the same folder of the old file
  • I edited the file “/etc/rc.local” by entering the new server file name in place of the old one
    Is this update procedure correct or is there something else I should do?

Do you have any suggestion to help me solve the problem?

Thanks

I found the problem!
I changed this row in my sketches

Blynk.begin(auth, server_ip, 8442, arduino_ip, dns_ip, gateway_ip, subnet_mask, arduino_mac);

into

Blynk.begin(auth, server_ip, 8080, arduino_ip, dns_ip, gateway_ip, subnet_mask, arduino_mac);

Now it works… probably the comunication port has been changed in the new server.

Bye
