Jenkins Setup Wizard Blank Page

After getting Jenkins Setup Wizard Blank Page http://localhost:8080/index works for me.

I experienced the same problem but a simple restart fixed it .

Just try this :-

sudo service jenkins stop
sudo service jenkins start

targeting the url to https://../jenkins/index appeared to solve the problem in most cases.

even if the first time, Browser's back button once on the blank page after the wizard finished sent me to the working page: http//:websiteDomain/login?from=%2

In my case I used (jenkins/jenkins lts) the official docker image
