How to configure this

I need to tell brief story.

I have a cloud node service provided by elephantsql.com

My cloud pgsql instance successfully connected with "SQL Manager (EMS)"
tool. This tool is alternative option to PgAdmin tool.

But same instance did not connect with PgAdmin ... error - Fatal: Password
Authentication Failed for user 'user'.

I have application in MS Access. The ODBC test button on MS Access ODBC
connection form initially gave "Connection Successful" message. But just
after moments, I got another message that connection crashed "pg_hba
config...." message was like that.

Afterwards, any ODBC connection attempt in MS Access (also MS Excel)
started giving the message of "Fatal: Password Authentication Failed for
user 'user' .

But .. SQL Manager (EMS) can always be successfully connected from home
laptop.

In office with proxy settings .... It is not connected even with SQL
Manager ... On every tool, it gives error "Could not translate host name to
address. Unknown server error."

So there are multiple things. Server is up and running. But can be
connected only from one tool and that also only on home laptop.

So Sirs, is it a bug or just a case of configuration. If config ... Which
thing to be configured and how?
