psql SQL STATE[08006] Password Authentication Failed for User. Laravel - laravel

Question

This is my first time working with Laravel, and I have a project set up, but I cannot connect to the database I created in Postgres. Whenever I try to connect to the database for a query (or anything), I get this error:
PDOException
SQLSTATE[08006] [7] FATAL: password authentication failed for user "marlie" FATAL: password authentication failed for user "marlie"
I'm using Windows 10, PostgreSQL 11, Laravel 6.0.4. I can connect to the database through pgAdmin4, command line, and psycopg2 without any password authentication issues. Only Laravel is giving me a hard time.
I've tried creating a new Laravel project, creating a new superuser (which I've tested, can successfully access the database from the other programs I mentioned above). I've also tried putting the username and password in both single and double quotes. I tried changing the database name to the OID number value in my postgreSQL file for the database. I've also tried adding the absolute file directory. I've tried changing port from 5432 to 54320. I've also tried other passwords.
Some search results suggested I play with the pg_hba.conf file and adding some lines such as (the indentation here is a little funny, but in the actual file it's all lined up):
local all marlie md5
local all marlie trust
host all all ::1/0 trust
host all all all trust
I've also tried changing everything to trust, in which case I can log in from command line without a password, but Laravel still won't let me! Also, my Windows laptop doesn't seem to support local connections since they're Unix-socket domains, so any local entries in pg_hba.conf end with the file not being able to load at all. Currently, my pg_hba.conf file is back to the default settings.
I've tried logging in by ssh into my Laravel project through Homestead.
$ vagrant ssh
$ psql -d natureFun -U marlie -W
Password:
psql: FATAL: Peer authentication failed for user "marlie"
I thought this was interesting because nowhere in my conf file do I say to use peer authentication. I've only ever tried trust and md5.
This is my .env file from Laravel
DB_CONNECTION=pgsql
DB_HOST=127.0.0.1
DB_PORT=5432
DB_DATABASE=natureFun
DB_USERNAME=marlie
DB_PASSWORD=secret
This is pg_hba.conf
# TYPE DATABASE USER ADDRESS METHOD
# IPv4 local connections:
host all all 127.0.0.1/32 md5
# IPv6 local connections:
host all all 127.0.0.1/32 md5
# Allow replication connections from localhost, by a user with the
# replication privilege.
host replication all 127.0.0.1/32 md5
host replication all ::1/128 md5

Answer 1

It seems that your first pg_hba.conf has a typo:
host all all all trust
Should be:
host all all <ip_address>/<netmask> trust
If it's a dev machine and you don't care about security (for now), just try:
host all all 0.0.0.0/0 trust
Also, unless you're acutally using IPv6, I'd recommend getting rid of the entire line containing ::1/0
Your second pg_hba.conf that you pasted should work, given that you restarted/reloaded the postmaster process -- you can usually do that through pg_ctl reload from the terminal or SELECT pg_reload_conf() from psql

SOLVED! I misunderstood how Homestead worked (and also failed to mention that I am using it, sorry!)
when I put localhost or 127.0.0.1 in my .env file in my Laravel project, it references the Homestead Virtual as the localhost, NOT my actual computer.
Changing DB_HOST to my computer's IP address solved the problem and I am now happily connected.
