Apache is crashing and auto restarting on digitalocean

I recently requested a change to my root password which was successful and I am able to use it on the console. However, my IP address stopped working. Both visiting my domain and SSH are responding with a connection timed out error.

It was working fine until my root password changed and the server was restarted.

I checked the error log using this command:

tail -50 /var/log/apache2/error.log

And this is what i got:

Notice the SIGTERM, shutting down? I think Apache is crashing and the service is auto-restarting.

At first I thought it was as a result of low memory usage then I checked with this command free -mh

here are the results. My Ram is enough:

              total        used        free      shared  buff/cache   available
Mem:           1.9G        259M        1.4G         612K        258M        1.6G
Swap:            0B          0B          0B

Firewall is inactive so nothing is blocking port 80

sudo ufw status
Status: Inactive

I also run this command to see what’s being listened on

sudo lsof -iTCP -sTCP:LISTEN -P

COMMAND    PID           USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
sshd      812           root    3u  IPv4  18468      0t0  TCP  localhost:53 (LISTEN)

master      1089           root    14u  IPv6  19479      0t0  TCP *:25 (LISTEN)

Could I be my Apache configurations?
here is what is being listened to on my /etc/apache2/ports.conf

grep "Listen" /etc/apache2/*.conf

etc/apache2/ports.conf: Listen 0.0.0.0

etc/apache2/ports.conf: Listen 433
etc/apache2/ports.conf: Listen 433

I can’t even restart apache it doesn’t let me

service apache2 restart

Job for apache2.service failed because the control proccess exited with error code. See "systemctl status apache2.service" and "journalctl -xe" for details.

On running that command I got this:

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

         apache-system.conf

Is this normal? Please help
