502 Whoops, GitLab is taking too much time to respond

I have Upgraded to 9.0.4-ce.0 from 8.0.5-ce.0, eversince I get a error page with following message “502 Whoops, GitLab is taking too much time to respond”

I have ran “gitlab-ctl reconfigure” several times, nothing seem to make any difference. I appreciate any hints to determine the cause and then fix it.

Below is the outout of “sudo gitlab-ctl status”

Hi,

Usually this means that you have a configuration issue somewhere, I would recommend that you copy your current settings into the latest template and reconfigure your installation.
