vboxweb-service fails preventing phpVirtualBox access

[elderpro]

I'm trying to understand what to do about correcting a vboxweb-service problem. I use phpVirtualBox for access to VirtualBox on an Ubuntu Server 18.04.

This setup works from boot up until vboxweb-service is restarted or started. Then phpVirtualBox stops working "An error occurred communicating with your vboxwebsrv." and "Could not connect to host (http://127.0.0.1:18083/)".

phpVirtualBox working

sudo  ps aux | grep vboxwebsrv
(…RETURNS)
vbox      1364  0.0  0.1 555468 14856 ?        Sl   14:47   0:00 /usr/lib/virtualbox/vboxwebsrv --background -H 127.0.0.1 -p 18083
sudo systemctl status vboxweb-service
(…RETURNS)

restart just the vboxweb-service (or also with vboxdrv and apache2 restarted at the same time)

sudo systemctl start vboxweb-service

phpVirtualBox stops working "An error occurred communicating with your vboxwebsrv."
and "Could not connect to host (http://127.0.0.1:18083/)"

sudo systemctl start vboxweb-service
sudo systemctl status vboxweb-service

or reboot the server and phpVirtualBox is again working

sudo  ps aux | grep vboxwebsrv
