Hi,
I have been working with my NodeMCU and firebase for a few weeks now, and up to a few days ago, it was working. The code below is for demo firebase provides and even that won't connect to my real-time database.

}
To my knowledge, the firebase library is up to date, so I'm not sure what the issue is. My internet is ok as the code for that works and prints my IP address. The sketch compiles fine, and uploads fine, just no connection to firebase.
Also, I apologise, I know there are a few of these types of topics, but I wasn't able to find anything that worked.
