Useradd: warning the home directory already exists

Hi,
I am trying to set up jitsi on Ubuntu and Plesk following the video on youtube (https://www.youtube.com/watch?v=8KR0AhDZF2A&t=196s)

I get this message after installing:

Setting up jicofo (1.0-508-1) …
useradd: warning: the home directory already exists.
Not copying any file from skel directory into it.
dpkg: dependency problems prevent configuration of jitsi-meet:
jitsi-meet depends on jitsi-meet-web-config (= 1.0.3729-1); however:
Package jitsi-meet-web-config is not configured yet.

dpkg: error processing package jitsi-meet (–configure):
dependency problems - leaving unconfigured
Processing triggers for systemd (237-3ubuntu10.39) …
Errors were encountered while processing:
jitsi-meet-web-config
jitsi-meet
E: Sub-process /usr/bin/dpkg returned an error code (1)

Would be very happy about help.

That is a warning and you can ignore it. Probably there is a problem with your webserver and reload of its config fails. Check that.

I can just about handle a server, not an expert. Could you be a bit more specific?

When I call my domain there is 502 Bad Gatway, nginx
