What is the error when outputting status apache2 code=exited status=1/failure?

Question

Apache HTTP Server

Hello, please tell me when I execute the command:
sudo systemctl status apache2the following output occurs:

Sites on the server seem to work, but this red error on the screen confuses me. Can you please tell me how to fix it?
Maybe this red inscription began to appear when I restarted apache2, with an error in the config of one virtual host, as a result, apache2 crashed, I removed the error, restarted, apache2 now seems to be working, but this red error confuses.

Thank you in advance for your response
