If you follow that link to the troubleshooting guide, it will tell you how to deal with this.

This error is with PHP Version 7.0.6.
If I change PHP to 5.6.17, it works.

I really don't know what's wrong....

Do what it says in the guide. That will allow you to work out what is missing or wrong with your config. It's quite likely to be something like a missing CA file in your PHP 7 config.
