How to remove default apache2 virtual host config?

Question

Apache HTTP Server

Good day to all!
I decided to get rid of the standard configuration file of virtual hosts 000-default.conf, after disabling it through a2dissite and connecting a new one, but when the service is restarted, apache gives the following:

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

By executing journalctl -xe, I got information about what swears on ports.conf, but the bottom line is that if I take the contents of the new virtual host and re-create 000-default.conf and push its contents there, the error will disappear

Ports.conf content:

# If you just change the port or add more ports here, you will likely also
# have to change the VirtualHost statement in
# /etc/apache2/sites-enabled/corp.conf
Listen 80
Listen 14799
<IfModule ssl_module>
        Listen 443
</IfModule>
<IfModule mod_gnutls.c>
        Listen 443
</IfModule>
# vim: syntax=apache ts=4 sw=4 sts=4 sr noet

I already tried to prescribe ServerName in apache.conf and in the new virtual host config, but nothing helps
. Tell me where to dig?
Server version: Apache/2.4.29 (Ubuntu)

He writes to you in English in white:

Nov 30 20:19:08 prxsrv apachectl[3805]: Cannot define multiple Listeners on the same IP:port

Bring your own config:

Listen 80
Listen 14799

Listen to either 80 or 14799.
