Things that I have tried:
System preferences > MySQL > initialize setup.
Checked Username is correct on AWS RDS set up.
Checked the endpoint address.
Tested connection on a 127.0.0.0 database. Works fine.

Sounds like you have not configured the Security Group related to your RDS instance. You must set up inbound rules for the security group to connect to the database. You can set up one inbound rule for your development environment and another for Elastic Beanstalk (assuming you use that to host your app). Setting up an inbound rule essentially means enabling an IP address to use the database. Once you set up the inbound rules, you can connect to the database from a client such as MySQL Workbench. For information about setting up security group inbound rules, see Controlling Access with Security Groups.

I have a free tier server on AWS's RDS that I created months ago for a project I've been messing around with. I had set up MySQL Workbench to connect to that instance had previously edited the database through that connection. However, I stopped working on that project and, in an attempt to start working on it again, I opened MySQL Workbench and tried the saved connection, only for it to fail and show the error "Your connection attempt failed for user [my username] to the MySQL server at [my instance's endpoint]:3306: Unable to connect to localhost".
I've checked the connection and I've confirmed that the endpoint is correct, it's using port 3306 as it should, and my login name and password are the same ones I use when I log into AWS directly. I've checked the instance and it reports that it is Available.
It seems like the most common solution for this issue is to check the inbound rules for the instance's security groups and make sure that my machine's ip address is added to it. When I look at that database's inbound rules, I see one, named default, that is set to allow all traffic using any protocol and port. The other is one I added when I initially set up the database and it is set to allow my machine's ip address, obtained using ipconfig. Despite this, I am still getting this error.
Does anyone see what I'm missing here? I can provide more details about my security groups and my database if that would help.

I can't connect to my Amazon Relational Database Service (Amazon RDS) DB instance.
There are a number of root causes for the inability to connect to an Amazon RDS DB instance. Here are a few of the more common reasons:
Tip: You can use the following troubleshooting steps to identify the source of the connectivity issue. Or you can use the AWSSupport-TroubleshootConnectivityToRDS AWS Systems Manager Automation document to diagnose the issue for you. This automation document can diagnose network ACLs based on the primary IP address of the Amazon Elastic Compute Cloud (Amazon EC2) instance, but ephemeral ports aren't verified. The automation doc also checks security groups based on the primary IP address of the EC2 instance, but that automation doesn't check specific ports. For more information, see Running a simple automation workflow.
Be sure that your DB instance is in the available state
If you recently launched or rebooted your DB instance, confirm that the DB instance is in the available state in the Amazon RDS console. Depending on the size of your DB instance, it can take up to 20 minutes for the DB instance to become available for network connections.
If your DB instance is in the failed state, see Why is my Amazon RDS DB instance in a failed state?
Be sure that your DB instance allows connections
Be sure that traffic from the source connecting to your DB instance isn't gated by one or more of the following:
Troubleshoot potential DNS name or endpoint issues
When connecting to your DB instance, you use a DNS name (endpoint) provided by the Amazon RDS console. Be sure that you use the correct endpoint, and that you provide the endpoint in the correct format to the client that you use to connect to the DB instance. For a list of DB engine connection tutorials that includes instructions on how to find and properly use an endpoint in various client applications, see Getting started with Amazon RDS.
For example, use nslookup to the DB instance endpoint from an Amazon EC2 instance within the VPC:
See the following example of a non-authoritative answer:
Troubleshoot database level issues
Check the route tables associated with your instance
When you create a Multi-AZ deployment, you launch multiple replica DB instances in different Availability Zones to improve the fault tolerance of your application. Be sure that the subnets associated with each DB instance are associated with the same or similar route tables. If your primary DB instance fails over to a standby replica and the standby replica is associated with a different route table, then traffic that was previously routed to your DB instance might no longer be routed correctly.
For more information about configuring route tables, see Configure route tables. For additional information about Multi-AZ deployments, see Multi-AZ deployments for high availability.
Note: If you can connect to your DB instance but you get authentication errors, see How do I reset the master user password for my Amazon RDS DB instance?
Verify the connectivity
Verify your connection by running one of these commands:
If either the telnet or nc commands succeed, then a network connection was established. This means the issue is likely caused by the user authentication to the database, such as user name and password.
