Valet This site can’t be reached, ERR_CONNECTION_REFUSED

The process has been signaled with signal “6”.

This issue happened for me for Laravel projects and I could solve it.

First of all do this:

composer global update

Then do this:

valet start

As you see php@7.2, nginx and valet services will be started.

Then check that the issue is resolved or not. If the issue is still there, you should do this:

Go to the project folder

cd your_project

then

valet start

you may see such this error:

The process has been signaled with signal “6”.

It’s not a big issue!

Just do this:

brew upgrade nginx

Then again in the project folder do this:

valet start

You might see such:

As you see here, dnsmasq, php@7.2 and nginx are restarted.

And everything will be fine!
