Two questions:-
- What does netstat -na | grep LISTEN | grep 80 show?
- Do you have an IPv6 address allocated? What do you get as output for ip a s ?
You may have it already available.
Please wrap all code, files, configurations, data, input & output/errors in CODE tags. It makes it easier to read, preserves spacing for indenting/fixed-width data and stops interpreting text as links, smileys, email addresses etc.
