Problem with comunication. Arduino + ethernet

Hi. This is my first post here and I want to say hello to everybody.

I have some problem with connection to the thinger. My set is arduino uno with ethernet shield w5100. This set is connecting with no problem using standard ethernet sketches - webserver, chat etc.

I also tried to include #define DISABLE_TLS. no success. On my shield there is 510 resistor so its ok. I believe my id, credentials etc. is filled correctly. Tried setting up device one more time , changes credential.
after putting #define DEBUG i get theese in serial monitor

[NETWORK] Starting connection…
[NETWORK] Initializing Ethernet…

Please help.
