Are you running a local web server on port tcp/80/443, otherwise why
connection to localhost? You need a server like apache, nginx, or whatever
web server listening on 80/443 for a browser to find a webpage on
localhost, which is your system. Otherwise the browser won't find a socket
to connect to let alone a web page, which is what it's telling you.
## this will show you anything listening locally on http|https ports and
what app did it
sudo ss -tpl | grep http
## try to connect if you think you should see an open socket from above,
below fails
[~]# telnet 127.0.0.1 80
Trying 127.0.0.1...
telnet: Unable to connect to remote host: Connection refused
No active firewall right?
If you wanted to you can limit host access to bind external sockets like
80/443, or whatever to only 127.0.0.0/8 meaning only local processes can
access sockets, not even someone on your local lan. This is a security
practice in application cases for high-speed caching or inter-process
communications local to this system only.
