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. -mb On Sat, Oct 9, 2021 at 12:24 PM Michael via PLUG-discuss < plug-discuss@lists.phxlinux.org> wrote: > the browser shows the error as: > The site could be temporarily unavailable or too busy.
