Advanced Template Testing. Acceptance tests failed

Hi guys !

I have started using CodeCeption on my Yii2 installation and have failed these at once. 5 acceptance test made a next error - ‘Curl Error 7’ (error 7 = Failed to connect() to host). I tried to change ‘homeUrl’ in main-local to ‘homeUrl’=>[’/’], but this did not help me at all.

What went wrong?
