How to set up signed SSL Root and Leaf certificates on Ubuntu 18.10 Postgresql 11 Database and Windows 10 Power BI plus PostgreSQL?

I have Power BI and PostgreSQL 11 installed on Windows 10 and my primary PostgreSQL 11 database on Ubuntu 18.10 Linux. I edited the postgresql.conf and pg_hba.conf files correctly to the IP Adresses my Windows 10 computer uses with PostgreSQL 11 and Power BI to connect to my PostgreSQL 11 Ubuntu database. However, I got errors in Power BI while I could manually connect via command line.

After troubleshooting with Microsoft Support, I was told:

However, I am confused by the tutorials at

• 34.19. SSL Support and
  
• Connect to PostgreSQL over SSL/TLS on Debian/Ubuntu - gab.lc.
  

I can't tell what steps need to be done on my Ubuntu PC and what steps need to be done on my Windows PC. I don't know if special steps are needed to configure Power BI with the certificates. How do I set up my bidirectional certificates?

Can someone offer a very detailed tutorial, tell me 'how' to read a tutorial, or explain the steps in an answer please?

Certificate error: "Content is blocked because it is not signed by a valid security certificate" with IE11 and Windows 10.

Original Title: Certificate errors with IE11 and Windows 10.

Hi,

I am getting a "Content is blocked because it is not signed by a valid security certificate" message when I try and go to website that I know is safe and have no problem getting to with Firefox. I tried everything I can think of to fix this, adding to trusted
sites, unblocked the certificate check etc etc. Has anyone figured out why this is happening??

Thanks!
