Main medplum app still points to [api.example.com ](https://api.example.com/fhir/R4/$graphql) on network debugging even if I already configured medplum.config.json unlike "Build from scratch" docs where I could rebuild the whole medplum app with node after config changes, I am not sure where sudo apt-install medplum installed the medplum app frontend to trigger node build and update the config url references my self hosted api route with a dedicated url is working with no problems

Hi @mrbouncybear - you should have been prompted for "API Server Hostname" during the deb installation process. You should be able to trigger it again using:

sudo dpkg-reconfigure medplum

OHH I remember now I had a problem like I accidentally pressed ALT+ Backspace when that appeared I couldn't bring it up anymore even if I reinstalled medplum from apt Will try dpkg-reconfigure Thank you for this and will let you know
