I have a PostGIS DB at a remote server and I can connect to it from my desktop using pgAdmin4. However, when I try to connect though QGIS (v3.4) I get an error:

FATAL: no pg_hba.conf entry for host "10.1.<complete ip here>..., user "car_r" database "car", SSL off

The funny thing is that my computer is listed on the server pg_hba.conf or else I would not be able to connect using pgAdmin4.

Any idea what could be wrong?

Adding more info

My PostGIS server is setup to accept only secure connections (hostssl in the pg_hba.conf). When I force QGIS to use SSL, (SSL mode: require) I get a "SSL error: certificate verify failed" error.

How can I make QGIS recognize my server certificate?

  • is 10.1.x.x the only ip address your machine has? do you have ipv6 enabled? what is the relevant line from your hba file?

  • Our network has ipv6 enabled. I don't have access to the pg_hba.conf file so I don't know how it was done on the server. Will go after my sysadmin.

  • do you type a passwd in pgadmin4? - might be set to trust or peer which will fail when QGIS sends a password

  • I type a password on both pgadmin and QGIS

  • When I wrote that I type a password, I meant that I was using a password. But as I wrote in my answer, the problem happens when I save the password using QGis authentication.

Looks like I've hit a known QGis bug.

If we use authentication on the PostGIS connection (that is, store the password securely), the connection using SSL fails. If instead I remove my authentication and type the user/password every time, the connection works.

Here is the link to the bug report:
