Postgres connection to Server using IIS

i need help with this error:

Retry in 20s due to error: 28000: no pg_hba.conf entry for host " ...", user “postgres”, database “postgres”, SSL off

This is not a Survey Solutions error. This is a Postgres error. Correspondingly the Postgres-centered forums are more useful for resolving it. See, perhaps, here:

has a paragraph describing how to allow connection to a postgresql database.
