Hi,
I am making a project (on a NodeMCU) with a local Blynk server (on a raspberry pi) that is not connected to the internet and I was wondering if I can send notifications from the board to my phone.
Because when my local server is connected to the internet, everything works perfectly (with this I mean a piece of test code that sends a push notification to my phone).
But when it isn’t connected to the internet, I can’t send notifications. And I get the following error in the log:
“ERROR- Error sending push. Reason fcm.googleapis.com: Temporary failure in name resolution”
Is this because I am doing something wrong, or is it because it is not possible to send push notifications without an internet connection?
