How to fix Server Error, connect ETIMEDOUT after execute 'firebase deploy'

Question

I'm recently working with Firebase. After practice with some services, Iwanted to deploy my functions. However, every time I want to deploy it, a timeout error appears.

I'm working with Ubuntu 19.04 and the version of firebase cli is 7.3.0

This is the error, sometimes the timeout appears before and any line.

firebase deploy --only functions:helloWorld --debug

I use the services of hosting. I deployed an app with integration with firestore without any error. I want to know the reason of this problem.

Answer 1

I executed all the commands to deploy my functions in other machine and in other network. It's possibly that my internet is unstable.

At this moment, I'm using the integration of Github with Travis CI to deploy my functions and I have no problems by the moment.
