Site can't be reached anymore

I’ve started getting “This site can’t be reached” errors when trying to reach my site with a web browser. I can still ping it, log into it with SSH, and run a PHP script with the command line. Nothing new appears in the Apache error log after an attempt to reach it with a web browser. It uses a PostgreSQL database, which I can still access with the psql command, but not with PGAdmin anymore. What else should I look at to figure out why this is happening? I took a screenshot of output from the top command in case that could be helpful.

You can check if the Apache workers have been exhausted by any chance. This information will be stored in the error_log file.

  • grep -i workers /var/log/apache2/error.log

If this is the issue you should see a similar output of the command:

server reached MaxRequestWorkers setting, consider raising the MaxRequestWorkers setting
