PG::ConnectionBad (FATAL: password authentication failed for user ) on rails s and DBeaver

Question

Why am I getting this error on when running "rails s" and while trying to access the database via DBeaver? It was running yesterday on DBeaver with the same credentials.

My pg_hba.conf file looks like this, "peer" isn't set anywhere as a method and I've tried "md5":

 # "local" is for Unix domain socket connections only local all all scram-sha-256 # IPv4 local connections: host all all 127.0.0.1/32 scram-sha-256 # IPv6 local connections: host all all::1/128 scram-sha-256 # Allow replication connections from localhost, by a user with the # replication privilege. local replication all scram-sha-256 host replication all 127.0.0.1/32 scram-sha-256 host replication all::1/128 scram-sha-256

If I try logging in with psql -U username -W, I enter my password then see this:

psql: error: FATAL:  Peer authentication failed for user "ryalto"

Credentials are all correct, I've also tried "sudo service postgresql restart".
