Can't Connect Arduino to Blynk using Ethernet (Login timeout)

Need Help With My Project
1

Hello guys, i’m kind of new in here and i need help in connecting my Arduino Mega to Blynk using the arduino ethernet shield. I just run the simple example (Arduino_Ethernet) from Blynk library and the serial monitor shows the following:

[0] Getting IP...
[6095] IP:192.168.0.104
[6096]

        /___/ v0.5.2 on Arduino Mega

[6209] Connecting to blynk-cloud.com:80
[9353] Login timeout

THANK YOU!

And search the forum. There are plenty of topics regarding connection issues. Most of them starts from instructing the user how to check connection with simple ping command… :wink:

There is no simple solution for your issue, unfortunately

I pretty sure i read all of them before i got here. I tried debugging everything i have, but still no result. I’m just connecting the ethernet shield to the router but i have no connection, just a “login timeout”. Did you ever encounter anything like that?

Try to guess! :wink:
… but ALWAYS it was related to network connection issues. And SOMETIMES other users reported the ETHERNET shields just don’t work (mine DOES work). But it’s all here… somewhere

This is a very common error that simply means NO connection to Blynk server. Why there is no connection can be almost impossible for us over here to fix as it may simply be something in your network… try the troubleshooting and confirm you actually can communicate to the internet with that Ethernet board (use non Blynk sketches from the Web if need be).

Or just skip that Ethernet shield for now and try with the simple USB link…

I tried the ethernet shield by running the WebServer example. It works fine so i guess the ethernet shield is working properly.

and the PING command returns…?

This is what you should PING

But again… PLEASE use search. It has been answered a multitude of times.
I guess our developers should fill the gap in docs regarding this simple PING test. It is the starting point for anything further

I am pinging the address 192.168.0.106 (the one on the arduino shield) and i get:

You are pinging your shield, only heaven knows why… you should be pinging blynk-cloud.com :stuck_out_tongue:

I wasn’t sure what i’m doing :stuck_out_tongue: .
Anyway, i did ping blynk-could.com before with no issue.

Well, try the USB option… it basically turns your PC into an oversized Serial to Ethernet shield… if that works then you can go back to troubleshooting the actual shield. If it doesn’t work, then we have a better idea of the direction to look.

Alright well thank you! I will try this option and will get back to you.
