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.

Hello, @swadams

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

  1. 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
