Can't SSH into my Bitbucket repository - conq: repository access denied

I have followed a million guides regarding this and I cannot get it to work. Earlier, I successfully pushed via SSH to my private Bitbucket git repository, now suddenly it wont work.

I have recreated the keys with a new passphrase, added it to my Bitbucket settings and it wont work.

Okay, here are the steps I took:

1. Deleted old key pair (project1 and project1.pub)
2. Recreated it with this command ssh-keygen -f ~/.ssh/project1 -C "project1"
3. Created a config in ~/.ssh file for my two Bitbucket accounts, with the following contents:

#!

Host project1
 HostName bitbucket.org
 IdentityFile ~/.ssh/project1
Host project2
 HostName bitbucket.org
 IdentityFile ~/.ssh/project2

1. Grabbed the contents of project1.pub and created a new SSH key entry in my Bitbucket account.
2. Added ssh-agent in my ~/.zshrc plugin list like this: plugins=(git ssh-agent) and restarted Terminal
3. Did ssh-add -l and saw only project2 was loaded
4. Did ssh-add ~/.ssh/project1, entered my passphrase and success, like this:

#!

2048 SHA256:THESHA256 /Users/myuser/.ssh/project2 (RSA)
2048 SHA256:THESHA256 /Users/myuser/.ssh/project1 (RSA)

1. Restarted Terminal and did ssh-add -l and it listed both entries
2. Went to my project and did git push and it told me I had no access.

When I do ssh -T git@bitbucket.com, it tells me I'm logged in with the username of project2.

logged in as project2_user.

My system is OS X 10.11.5

I could never fix multiple identities on my computer and always used HTTPS, but I need to make everything more secure with SSH, which also allows my account to have two-factor authentication. Therefore using SSH is a must now and I don't know what to do.

P.S: I did the creating steps for the identity for project2 too, but I'm fairly certain that it doesn't work either.

Guide I followed:

https://confluence.atlassian.com/bitbucket/configure-multiple-ssh-identities-for-gitbash-mac-osx-linux-271943168.html

project2 has no passphrase, while project1 does! Just thought maybe this is relevant.
