hi friends

Hello. What error do you see?
Connect what? Hardware or phone?
un ?
when i am use the wifi network there is no problem but when i switch to mobile data the problem occurs
Maybe your mobile provider does not allow unknown addresses. On public networks I can’t connect to my private port forwarded server because of the protection from the public network.

This means the auth token is not valid. Maybe you have made a typo?

This message you get in the app? Or in serial of your hardware?
Then I don’t know either…
ohoo i’ts ok but thanks for the help!
@nikky it could be http://docs.blynk.cc/#troubleshooting-geo-dns-problem. Try to ping blynk-cloud.com from your home. Take IP and put it in app as described in link above. Please let me know if that helps.
i did step as per the above doc but it was not solved this r the screen shots of my phone
you need to ping blynk-cloud.com and take it IP.
ya actually i did it i enterted the ip which is displayed in the serial monitor but when i log in to app “something wrong happen msg” is being displayed
