I created droplet for Magento 2 and followed instructions from here:[https://marketplace.digitalocean.com/apps/magento-2-open-source]. I made steps until I received the message Installation complete. Access your new Magento site in a browser to continue.
So I go to my public ipv4 address [157.245.71.116](http://157.245.64.1/) where wasn’t magento page. Then I restarted server and from that moment on my ipv4 address displayed message with Error 503 Backend fetch failed.
I found this question from community. It looks very similar. So I go to /etc/default/varnish and tried to increase the http_resp_hdr_len and http_resp_size. After running service varnish restart problem with Error 503 Backend fetch failed still on ipv4 address.
Do you know how to fix it? Or could you help me to set up Magento 2?
