Can't access remote database (error says it's because of a bad internet connection) with EAS build

I use firebase for user authentication and as a database. I can launch my app through a regular expo cli setup and firebase works fine, but I need a native module, so I need to have a custom development environment and I have to build with EAS build, because I have difficulty launching my app locally. Is access to third parties through the internet supported with EAS builds ?

Thanks in advance
