We recommend you use the server-based download you can configure in the 
security options of Jenkins. It's been the default for a while now as well.

Re: Plugin checkUpdates not working, can't upgrade plugins

Hi,

This Jenkins system was set up behind an nginx reverse proxy.
After further analysis of nginx, I found this in nginx-errors.log:

Looking in /var/log/nginx-error.log , I found:

*2016/04/08 09:38:35 [error] 1176#0: *834969 client intended to send too
large body: 1079277 bytes, client: 8.8.178.110, server: jenkins.freebsd.org
, request: "POST /updateCenter/byId/default/*
*postBack HTTP/1.0", host: "jenkins.freebsd.org
", referrer:
"https://jenkins.freebsd.org/pluginManager/checkUpdates
"*

So it looks like 2 months ago, the update-center.json became big enough to
trigger this problem.

Setting the *client_max_body_size* value as specified in
https://wiki.jenkins-ci.org/display/JENKINS/Jenkins+behind+an+NGinX+reverse+proxy
solved the problem.
