Nexus 3 HTTPs on port 443

Hi,
I’m trying to install and configure Sonatype Nexus OSS 3.42.0-01. on Ubuntu 20.04
I need to configure it on 443 HTTPS port.

I configured all, and if I try to run it on the port 8443 it works fine.
But when I try to run on 443 I receive the error below:

2022-11-10 15:03:43,778+0000 ERROR [jetty-main-1] *SYSTEM org.sonatype.nexus.bootstrap.jetty.JettyServer - Failed to start

I know the problem is the bind on port <1024, how can fix it?
Thanks for your support

I solved it with this command:
sysctl -w net.ipv4.ip_unprivileged_port_start=443
