Command-line connection with VPN to remote PostgreSQL fails, other apps work

I am trying to connect to PostgreSQL database hosted on Azure programmatically. I am able to do so using apps like [PgAdmin](https://www.pgadmin.org) or [Postico](https://eggerapps.at/postico/) . However, the connection does not work with psql or python. I have the error :

psql: error: could not connect to server: server closed the connection unexpectedly
	This probably means the server terminated abnormally
	before or while processing the request.

I am using a VPN (GlobalProtect v5.1.5-20) on MacOS 10.15.7. If I turn the VPN off and reboot my computer, the exact same psql command does work. Therefore, I don't think it's related to the database server. My main issue is that I don't know where to look at in order to debug. What I've done so far: - Checked the log of Postgres server: can't see my connections attempts. - Checked pg_stat_activity table and can't see any connections from my IP (except the one made with Postico) - Checked with LittleSnitch whether python / psql were able to connect to server. It seems that is the case. - UPDATE: Connecting to Postgres db from a Docker container running locally does work (with or without VPN). Any thoughts ? UPDATE 1, my routing tables * with VPN
