Why do I get - Failed to resolve com.squareup.retrofit2: retrofit:2.3.0

Here is my code, I am follwing a tutorial on making a login for my app but when I got to this stage I get errors.
dependencies {
implementation fileTree(include: ['*.jar'], dir: 'libs')
implementation 'com.android.support:appcompat-v7:28.0.0-alpha1'
implementation 'com.android.support.constraint:constraint-layout:1.1.2'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.2'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
implementation 'com.sqaureup.retrofit2:retrofit:2.3.0'
implementation 'com.sqaureup.retrofit2:converter-gson:2.3.0'
}
Any ideas?

The spelling of square word is wrong, so change it to this:
implementation 'com.squareup.retrofit2:retrofit:2.4.0'
