symfony server:start command throwing an error

Question

I try to run

symfony server:start

It returns an error message

The local web server is already running for this project at port 8000

But lsof -wni tcp:8000 isn't returning anything, I'm sure there isn't any softwares using the port 8000.

Starting by doing

bin/console server:start

is working like a charm.

Answer 1

symfony server:start writes a pid file to ~/.symfony/var/.

Remove the correct pid file (i.e the one that references the current project dir)

Answer 2

You can make a

symfony server:stop

The system reboot and symfony serve will works again.
