Quiz: nginx

Question 9 of 10

One correct answer

The application was moved to a unix socket, and `proxy_pass` holds `http://unix:/run/shop/shop.sock`. error.log says `(2: No such file or directory) while connecting to upstream`. What does it mean?

nginx did not find the site's page file.
There is no socket file at the path from proxy_pass — compare the path: ls -l /run/shop/.
The application did not answer in time.
www-data may not write to the socket.
