You may want to look at setting up a reverse proxy in front of Jenkins,
offloading TLS.

Changed port to 8443. That seems to have fixed it.
Thanks

Trying to guess:
" java.net.SocketException: Permission denied"
this smells of Java not running with enough privileges to open ports below 1024
Usually on Linux systems only root can open such ports.

I am setting up jenkins on an CentOS 8 machine. Currently have one running
under Ubuntu 16.
On the new machine, I am unable to get HTTPS working, even tho the config seems
the same as the other machine.
My partial config file is
# cat /etc/sysconfig/jenkins

I am quite certain I have the key store correct
I set up with
keytool -genkey -alias
servername.mydomain.com<http://servername.mydomain.com> -keyalg RSA -keystore
/etc/jenkins/jenkins.jks -keysize 2048
Then generated a CSR, had it signed by our internal CA.
Also imported the certificates for the CA's.
I have the following errors
$ cat /var/log/jenkins/jenkins.log
Running from: /usr/lib/jenkins/jenkins.war

I also tried extracting the key and cert and tried the following
/etc/alternatives/java -Dcom.sun.akuma.Daemon=daemonized
-Djava.awt.headless=true -DJENKINS_HOME=/var/lib/jenkins -jar
/usr/lib/jenkins/jenkins.war --logfile=/var/log/jenkins/jenkins.log
--webroot=/var/cache/jenkins/war --daemon --httpPort=8080 --httpsPort=443
--httpsListenAddress=0.0.0.0 --debug=5 --handlerCountMax=100
--handlerCountMaxIdle=20 --httpsCertificate=/etc/jenkins/jenkins.cer
--httpsPrivateKey=/etc/jenkins/jenkins.key
Same errors.
I disabled selinux. Did not help.
Tried linking /etc/alternative/java (default in the search path ) to Oracle 8
Java, OpenJDK8 and OpenJDK11. No luck.
Appreciate any advice.
Thanks
