UNABLE TO CONNECT TO A DATABASE IN A WEB SERVER.

I am writing a web app which should connect to a database in a server within
my personal network but I am having trouble. I get the following error
message:

There is no record on pg_hba.conf for 192.168.1.77, user postgres, database
restaurant, SSL inactive.

I have checked the configuration files on the server machine as follows:
* The listen_addresses parameter in postgresql.conf equals *.
* The pg_hba.conf has an entry of type=host, database=all, user=all,
IP-Address=192.168.1.77/32, Password=md5.

I have tried changing the IP-Address to 192.168.1.0/24 and 192.168.0.0/16;
also I tried Password=Trust and Password=Password.

What else can I check?

Respectfully,
Jorge Maldonado
