Connect your databases to Briefer and fetch data from them.
You can access the "data sources" page using the button on the bottom left corner of the interface.
psql
and make sure you can connect to it using the same credentials you provided to Briefer.
In case you’re still having trouble, double check whether your data source is behind a firewall and whether you need to add Briefer’s IP addresses to your firewall’s allowlist.
Finally, if you can’t connect to your data source using the native connector, you may want to try connecting to it manually using Python code.
