Cannot push to migrated Hawk project (wrong login)

When I log into Gitlab through gitlab.eclipse.org, I am logged in as @agarciad1 and not as @agarciad. This means that I cannot add my usual SSH key to my account, so I cannot push. When I try to push, I get this:

remote: 
remote: ========================================================================
