I tried stopping apache and it worked this time. Does this mean I'll have to go in and stop apache and renew it in close to 54 days? Or will it be automatic? Since it only works if Apache is not running.
/etc/init.d/apache2 stop
Stopping apache2 (via systemctl): apache2.service.
root@localhost:/var/www/server2.openspace.greenrobot.com/public_html/wp-content/plugins/openspace-server# certbot renew --cert-name server2.openspace.greenrobot.com --dry-run

Congratulations, all simulated renewals succeeded:

Thank you for your help.
