Could not connect to host (http://127.0.0.1:18083/)

[PartisanEntity]

Server: Ubuntu 20.04 LTS

Virtualbox Version: 6.1.26r145957

VBoxManage list extpacks

Extension Packs: 1
Pack no. 0:   Oracle VM VirtualBox Extension Pack
Version:      6.1.26
Revision:     145957
Edition:
Description:  Oracle Cloud Infrastructure integration, USB 2.0 and USB 3.0 Host Controller, Host Webcam, VirtualBox RDP, PXE ROM, Disk Encryption, NVMe.
VRDE Module:  VBoxVRDP
Usable:       true
Why unusable:

When checking the status of vboxweb.service:

systemctl status vboxweb.service

● vboxweb.service    Loaded: masked (Reason: Unit vboxweb.service is
masked.)     Active: inactive (dead)
If I try to manually start the service:

sudo systemctl start vboxweb

Failed to start vboxweb.service: Unit vboxweb.service is masked.

phpvirtualbox config.php:

/* Username / Password for system user that runs VirtualBox */
var $username = '***';
var $password = '***';

/* SOAP URL of vboxwebsrv (not phpVirtualBox's URL) */
var $location = 'http://127.0.0.1:18083/';

/* Default language. See languages folder for more language options.
 * Can also be changed in File -> Preferences -> Language in
 * phpVirtualBox.
 */
var $language = 'en';

/* Set the standard VRDE Port Number / Range, e.g. 1010-1020 or 1027 */
var $vrdeports = '9000-9100';

The user in the config.php is part of the vboxusers group.

The files in the phpvirtualbox web folder belong to this user.

phpvirtualbox error in the browser after logging in with admin/admin (I have also tried the username and password of the user configured in the phpvirtualbox config.php):

Exception Object
(
    [message:protected] => Could not connect to host (http://127.0.0.1:18083/)
    [string:Exception:private] => 
    [code:protected] => 64
    [file:protected] => /mnt/raiddisk/public_html/phpvirtualbox/endpoints/api.php
    [line:protected] => 134
    [trace:Exception:private] => Array
        (
        )

    [previous:Exception:private] => 
)

If I try to look for errors in systemctl:

systemctl --failed

vboxweb-service.service loaded failed failed vboxweb-service.service

I have no idea what else to try. I have installed virtualbox directly using the sources from the virtualbox website. I have also tried uninstalling and reinstalling everything.

From what I can tell the vboxweb-service.service is failing to start. But there is no helpful error message to understand why.

File "/usr/lib/virtualbox/vboxwebsrv" is missing from the Linux installer "virtualbox-6.1_6.1.26-145957Ubuntueoan_amd64.deb"

Thanks. I have copied vboxwebsrv to /usr/lib/virtualbox and rebooted. When I try to start vboxweb with

sudo systemctl start vboxweb

I still get:

Failed to start vboxweb.service: Unit vboxweb.service is masked.

[snk0752]

unmask the service systemctl unmask vboxweb-service systemctl enable vboxweb-service systemctl restart vboxweb-service

…
