Aldo :-) P.S. Furthermore in ..../apache2/error.log I find: PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php/20151012/apc.so' - /usr/lib/php/20151012/apc.so: cannot open shared object file: No such file or directory in Unknown on line 0 Il giorno Mon, 19 Feb 2018 12:48:25 -0500 Greg Wooledge <wool...@eeg.ccf.org> ha scritto: > On Mon, Feb 19, 2018 at 06:36:01PM +0100, Aldo Maggi wrote: > > Anyway, now if I browse writing my IP I get the Apache default page > > (the browser tells me, anyway, that the site is unsecure), if I > > write the name of the site I get (traslated from Italian): > > Unable to reach the site > > Connection denied by mysite.com > > "Connection refused" (the correct English translation) means that > either the service is not listening to that port, or the packets > were rejected by a firewall. > > You will need to examine both of those possibilities. > > Making sure the service is listening on :443 should be fairly easy. > You can use "lsof -i :443" for example, or some ss or netstat command. > > Checking whether you have a firewall blocking incoming 443 will be > a bit harder. >
