j_acegi_security_check is not accessible

[Jarno Hämäläinen]

Dear Jenkins users

I installed latest Jenkins of the Ubuntu 16.04 machine as instructed in https://wiki.jenkins-ci.org/display/JENKINS/Installing+Jenkins+on+Ubuntu

I got it running (sudo service jenkins start) and I'm able to open it by browsing http://<ip-of-my-server>:8080

The problem I'm facing is that when I configure Global Security to use Jenkins’ own user database and I try to add users, I found out that if I'm trying to log in the browsers requests http://<ip-of-my-server>:8080/j_acegi_security_check that does not respond at all.

E.g. Chrome says 'This site can’t be reached'

Any ideas what is wrong?

The Jenkins version is 1.651.2
