Jenkins stuck after clicking on creating a new user.

Then I decided to cancel that and what I saw in landing page is that css styles did not load properly. See attached screenshot.

Below is my /etc/nginx/conf.d/jenkins.conf

***********************************************************

Also I had to disable CSRF because of crumb issue in systemd:

/etc/systemd/system/jenkins.service.d/override.conf

*********************************************************

[Service]

Environment="JAVA_OPTS=-Djava.awt.headless=true -Dhudson.security.csrf.GlobalCrumbIssuerConfiguration.DISABLE_CSRF_PROTECTION=true"

*********************************************************

Also, I notice I cannot change the config.xml in JENKINS_HOME: /var/lib/jenkins
I do:

sudo systemctl stop jenkins

Copy new file by replacing ( I wanted to disable security)

sudo systemctl start jenkins

And I see my changes did not persist. They were reverted.

Please assist with that as well.
