Network problem with arduino

hi everybody
I use the blink app with a arduino uno. I have put the auth code in the software. I can see the arduino is connected ( I can see the IP address in my router) But Blynk says ’ your arduino uno is not in network’
Everything has worked in the beginning of this year but suddenly it didn’t anymore.

Can anyone help me ?


Try to use latest blynk library.

Update library

Thanks !!!
I did install the newest blynk library and it works again !!!
