Codeception: Codeception\Module\Yii2 can't open external URL though can be opened by browser

What are you trying to achieve?

I’m trying to get my REST endpoint working. The following url gets 200 response in REST clients.

http://sign-up-api.local/v1/user/info

What do you get instead?

I’m getting this exception.

Codeception\Module\Yii2 can’t open external URL
