I am running Ubuntu 20.04 as a web server on a cloud instance. There I have installed apache 2. Daily, I need to restart the instance or the apache2.service to restore access to the website.

sudo systemctl status apache2.service

● apache2.service - The Apache HTTP Server
     Loaded: loaded (/lib/systemd/system/apache2.service; enabled; vendor preset: enabled)

Hello, @jllandivarscott

I will recommend you examine the Apache error_logs in order to track down the exact issue.

To examine log files for errors while troubleshooting Apache on a Fedora, CentOS, or RedHat server, examine the /var/log/httpd/error_log file.

If you are troubleshooting a Debian or Ubuntu derived system, examine /var/log/apache2/error.log for errors using a tool like tail or less. For example, to view the last two lines of the error log using tail, run the following command:

  • sudo tail -n 2 /var/log/apache2/error.log

Substitute the number of lines that you would like to examine in place of the number 2 in the command. On a CentOS or Fedora system, the log file to examine is /var/log/httpd/error_log.
