Maven cannot download from Artifactory Repository - maven

Question

I am attempting to connect our Jenkins servers to our Artifactory repository for builds. I've been successful with the Jenkins server at my office location, but I am having problems with a Jenkins server that's on another part of the corporate network.
I've disabled the job, went into the workspace, and tried using mvn directly:
$ mvn clean

However, if I attempt to fetch that URL via curl, it downloads without any problems. Same with wget:
$ curl http://repo.vegicorp.net/artifactory/plugins-release/org/apache/maven/plugins/maven-clean-plugin/2.4.1/maven-clean-plugin-2.4.1.pom

So, I am able to reach that URL via wget and curl, but Maven itself seems to be having problems fetching that URL. I've added a proxy settings to my ~/.m2/settings.xml, but that doesn't seem to make any difference. We originally setup our Maven repository to redirect from Port 80 to Port 8080, but adding or removing the port number from the URL makes no difference. The settings.xml is from Artifactory which will generate it for you. The same settings.xml works in our office.
Removing the settings.xml allows everything to work because it can download from the standard Maven repo.
My settings.xml:
<?xml version="1.0" encoding="UTF-8"?>

That looks like a proxy settings problem. Can you please add the ouptut of mvn help:effective-settings to the question? Thanks!
I'm going to cry...
$ mvn help:effective-settings

Sorry. I can't run mvn help:effective-settings because of my settings...

Answer 1

Yet I don't know why, but after i restarted the nexus process, even before it truly started, maven download process continued.......
my environment: centos 7 , maven 3.6.3, java-1.8.0-openjdk-1.8.0.302
