Jenkins 2.263.4 LTS
Ubuntu 18.04 LTS
Freshly installed Jenkins returns an error "Unable to connect to Jenkins" after chosing "Install suggested plugins" during initial setup through wizard.
The server is able to reach https://updates.jenkins.io/current/update-center.json and http://updates.jenkins-ci.org/update-center.json (the former configured by default)
Also I've tried latest weekly build and jenkins:jenkins docker container an always got the same behaviour
Upd: Stacktrace (/var/log/jenkins/jenkins.log) can be found here: https://pastebin.com/nJ9XzbJY
Upd2: `--httpKeepAliveTimeout=60000` "removes" the exception, but wizard still isn't working and returns an error as indicated above
It's a duplicate of https://issues.jenkins.io/browse/JENKINS-46776 but I've decided to create a new issue to attract attention.
In my case RTT of request was about 1.76min (firefox stats). I understand that such problem caused because of slow VPN and ugly server, but that blocks installation process without any explaniations
JENKINS-46776 Setup wizard timeout for "Install Plugins" step is too short on slow systems or connections
We close duplicate issues as "duplicate". You're welcome to vote on the other issue as a way to express your desire that someone should volunteer their time to test all the places where Jenkins might fail over a low bandwidth or high latency network connection.
A round trip time of over 100 seconds seems like it will cause many different components of Jenkins (Blue Ocean, plugin manager, etc.) to fail.
