Welcome to the forum @ThaiMinh120

You will need to provide a lot more information

  1. What hardware/OS are you running node-red on?
  2. What version of node-red and of nodejs (use node -v to find that)
  3. What node have you installed to provide the firebase connection (possibly node-red-contrib-something)?
  4. Export those two nodes and paste them here. See this post for more details - How to share code or flow json

node red V2.2.2
I tried "add firebase" and "firebase modify on" but still disconnected.
I use node-red of IOT 2050 SIEMENS to connect with FIREBASE

Hi, I suggest you to use an updated Firebase palette because many palettes no longer work or don't support different URLs.

I recommend the following:

You will find the documentation on the Wiki.

I can't download node red of you

It would be helpful to know more. What do you mean? Do you have an error in the logs? ...
