Apache2 server on Ubuntu
I had Apache2 installed and it works fine and I can access my web page from anywhere but yesterday I cannot access it. I tried to restart Apache2 and it gave the following message:"Could not determine the server's fully qualified domain name, using 127.0.0.1 for ServerName". I edit the apache2.conf file to add the ServerName and restart apache2, the message was gone but I still cannot connect to the server. The error message returned by my name server was: "The following error was encountered:
Connection to 18.104.22.168 Failed
The system returned:
(110) Connection timed out
The remote host or network may be down. Please try the request again."
I also lost SSH connectivity at the same time, which had been working for the past three months. Everything just suddenly falls apart. Are there anybody give me a clue on what had happened?
