gitlab not executing git command from git

Question

I have successfully installed GitLab Community Edition 8.15.2 (omnibus) on my local ubuntu server 16.04 with apache2 (2.4), i can access it in browser and can perform all tasks. But when i try to execute task (like pushing project for first time or cloning project) using git bash or git gui, it does not perform the task e.g.

git clone http://192.168.179.128/pherry/Pilzon.git

it gave following output

Cloning into 'Pilzon'...
fatal: unable to access 'http://192.168.179.128/pherry/Pilzon.git/': The requested URL returned error: 500

So i looked into production.log file when i executed the following line

git clone http://192.168.179.128/pherry/Pilzon.git

and this was the log

then it asked for password and when i provided it and this was the log

i have been searching for solution for a day and have not found it yet.

You have a similar issue with 22532, alluding to a gitlab-workhorse mismatch version after an upgrade..

Issue 23133 also mention the JWT::DecodeError (Nil JSON web token) error message and points to gitlab-recipes issue 57, with the possible fix:

Short answer, need to change /etc/init.d/gitlab so gitlab-workhorse listens on a TCP port rather than using unix sockets, then set up an Apache rewrite to that port.
