Major Jenkins told me reverse proxy setup is broken, but the older version is OK.
So I use this command from wiki: curl -iL http://your.reverse.proxy/jenkins/administrativeMonitor/hudson.diagnosis.ReverseProxySetupMonitor/test
Here is my apache configure:
<VirtualHost *:80>
ServerAdmin webmaster@localhost
DocumentRoot /var/www/html
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
ServerName localhost
ProxyRequests off
ProxyPreserveHost On
SetEnv proxy-nokeepalive 1
ProxyPass /jenkins ajp://127.0.0.1:8009/jenkins nocanon
AllowEncodedSlashes NoDecode
</VirtualHost>
And here is what I saw:

[JENKINS-23774] Jenkins ver. 1.572 has an exception in hudson.diagnosis.ReverseProxySetupMonitor.
I am fixing the NPE, but this is not the real problem; it is just that 1.552+ requires you to pass Referer, which the originally documented curl command failed to do. I updated the wiki to correct the diagnostic command. As to what your actual proxy problem is, I am not sure yet, but perhaps when running the correct command you will be able to see.

Thank you. My OS is ubuntu 14.04(in the docker) with openjdk-7-jdk
I followed the new wik, but saw some strange characters and question marks, maybe not utf-8 ?

abcfy2: HTTP 401 is 'Bad Credentials', so verify that. I could only reproduce this when passing wrong password/username.
(Also, your not managing to make this work does not necessarily constitute a bug. If you have questions how to fix this issue, please ask on IRC or the mailing list.)
The request's referer does not seem to be set. Are you using some kind of "privacy protection" software? Anti-Malware with web-related features? What web browser and OS (in which versions?)
