I am using the image for virtual machine in order to create a test environment, I installed the sample data and make it work, the website is working correctly until I try to install an extension for the website or run setup:upgrade. Every time I try to do something I get 503 error.
Error 503 Backend fetch failed
Backend fetch failed
Varnish cache server
Please, could you help me?
