Here is some problem with your IP. Try to change from

192,   168,   1,  70

to another. Maybe this one is busy.

33

tried already several and im tryinng others too, i receive that message always

[] Using static IP
[1300] My IP: 0.106.106.106
[0] Blynk v0.3.1
[0] Using static IP
[1300] My IP: 0.106.106.106
[5001] Connecting to cloud.blynk.cc:8442
34

Try

IPAddress arduino_ip ( 192,   168,   1,  62);

this one is out of DHCP pool.

35

yeah the same thing… what a mystery :sweat:

36

Did you restart your router already? Sometimes it helps. I’m out of ideas. The thing is - your router doesn’t give Arduino correct IP.

37

yeah restarted and reseted… maybe i should abandone the ethernet shield and go for a wifi shiel or would i have the same problem?

38

but its strange cause i have the official ethernet shield rev2, i can connect form my laptop to the cloud and never had a problem connecting devices to my network, never used ethernet tough except for my tv recorder that my provider set up for me but it works great…

one last time this is the code that im using, i think everything is ok…:

@vshymanskyy any ideas?

This is my physical connection, the grey one without the protection is connected to arduino

hello there.
I started with the ethernet shield and blynk . i have been facing the same issue and had been struggling with it for the last 100hrs. After some RnD, i stumbled upon your post and found that i am having the exact issue just like yours.

the last sketch as u tried, my serail monitor showing this

[0] Using static IP
[0] Blynk v0.3.1
[1300] My IP: 0.0.0.0
[5001] Connecting to 10.0.0.10:8442
[10002] Connecting to 10.0.0.10:8442
[15003] Connecting to 10.0.0.10:8442
[20004] Connecting to 10.0.0.10:8442
[25005] Connecting to 10.0.0.10:8442
[30006] Connecting to 10.0.0.10:8442
[35007] Connecting to 10.0.0.10:8442
[40008] Connecting to 10.0.0.10:8442
[45009] Connecting to 10.0.0.10:8442

42

What is

10.0.0.10

and what is

[1300] My IP: 0.0.0.0

?

This is the sketch that i uploaded and the serial monitor gave the earlier mentioned output

@djinn111 Well, you using another person router IPs. You should use yours. Have you tried simple sketch without any settings?

45

yup, and i keep getting
[0] Blynk v0.3.1
[0] Getting IP…

46

Any idea guys? If i use a wifi shield will i getthe same error?

47

@djinn111 @Dmitriy i was checking the ethernet shield for weak solder points and found out that it has the w5500 chip instead of the w5100 that i specifically ordered… Also found this:

http://forum.arduino.cc/index.php?topic=329990.0

which says that i have to update the wiznet library or use the IDE from arduino.org. fonna give it a try when i get home.

Cheers

48

damn. thnks fr tht tip…chkd ur msg, n wnt on 2 chk my shield…sme prob in mine 2…

49

also found this

i don’t know how to install it though…

@vshymanskyy @Dmitriy help? i was able to get an ip using the ethernet 2 dhcpAdressPrint but in the blynk examples if i change the ethernet.h to ethernet2.h i get errors…

50

Anyone knows how to update using this files above?
