I'm trying to install Laravel valet but I keep getting (when I visit domain.dev):
It works! 
I already tried a lot. For example:
remove valet 
stop apache (apachectl stop)
composer global require laravel/valet
valet install
valet restart
But that does not work for me. I've also installed Laravel Homestead  in a vagrant box. Perhaps that has something to do with it? I can visit my Homestead sites. 
How can I fix this problem?
