Followed the link you posted and carried out all steps, also followed all the steps on the linked page to add exceptions and disable windows defender/firewall. I also added all mentioned files to 'Trusted Applications' in Kaspersky and added exceptions for each so they are not scanned (files, network traffic, etc.) but unfortunately it's still the same.
Really don't know what else to try
Just for completenesss I have pasted below the exact error message I receive:
Npgsql.NpgsqlException:

Note: I initially had PostgreSQL installed by the PT3 installer. I since removed it (PT3 and PostgreSQL) and installed PostgreSQL I downloaded from the link you provide on your site. As the Postgres user account was already created, during installation I had to enter the user account password as setup by PT3 (svcPASS83). The DB pass is the default used by HEM (postgrespass). I don't see this as an issue as HEM connects fine, it is only when LeakBuster tries to access the DB that it fails.
Any more suggestions?
Thanks.
