Solución:
Cambiar la configuración de Jenkins para desactivar AJP (Jenkins ya no usa AJP):
$ sudo vi /etc/sysconfig/jenkins
Localizar la sección relacionada con AJP y poner el puerto a -1:
## Type: integer(0:65535) ## Default: 8009 ## ServiceRestart: jenkins # # Ajp13 Port Jenkins is listening on. # Set to -1 to disable # #JENKINS_AJP_PORT="8010" JENKINS_AJP_PORT="-1"
Guardar los cambios y arrancar Jenkins.
