I don’t know why it has errors while it runs smoothly before, and I don’t think I change anything.

Thus, I would like to restart the server but it did not work. When I run “sudo supervisorctl restart all”, I’ve got the following error:

unix:///var/run/supervisor.sock no such file

Can someone please help?

Here is the fix for this problem:

sudo touch /var/run/supervisor.sock
sudo chmod 0700 /var/run/supervisor.sock
sudo supervisorctl restart all

I did this and now i get :

/opt/redash/current $ sudo supervisorctl restart all

unix:///var/run/supervisor.sock refused connection
