Answer 1

It does not make sense for your Magento backend to listen on port 80, because that's the port that Varnish is going to listen on.

The fact that this does not result in an error makes me suspect that Varnish isn't properly listening on port 80.

Once you can assure that Varnish is properly configured, could you attach the output of the following command to your original question?

sudo varnishlog -g request -q "ReqUrl eq '/'"

This command will print logging output for incoming Varnish requests for the homepage. Make sure you enabled debug mode in Magento, otherwise the X-Magento-Cache-Debug header will not appear in your response headers.

• Thijs Feryn: The screenshot provides an indication, but not the full picture. Can you please share the complete output of the log transaction. Preferably as a code block in your original question. Please also provide the full varnishd runtime parameters. If you're running varnishd via systemd, the systemd unit file is good enough. This extra context will help me better understand the issue.
