jENKINS WIth httpd reverse proxy

Hi i have setup jenkins behind httpd reverse proxy. I am able to get the unlock jenkins page. but wheni put in the admin password and click on continue it does not redirect to the next page… The page seems to get reloaded.
Here is my apache conf

ProxyPreserveHost On
ProxyPass         /jenkins  http://jenkinsip:8080/jenkins/ nocanon
ProxyPassReverse  /jenkins  http://jenkinsip:8080/jenkins/
ProxyRequests     Off
AllowEncodedSlashes NoDecode

# Local reverse proxy authorization override
# Most unix distribution deny proxy by default
# See /etc/apache2/mods-enabled/proxy.conf in Ubuntu
<Proxy http://jenkinsip:8080/jenkins/>
  Order deny,allow
  Allow from all

in /etc/sysconfig/jenkins i’ve added the following


Jenkins machine has a private ip only. Is there any additional config i need to add to allow reverse proxy
