Wrong projet url (http & ssh)

I have installed docker gitlab container.

From the project home interface i got as projet url :

http://user@serverhost/group/project.git

**But the correct url should be : **
http://serverhost:port/group/project.git

I added external_url on /etc/gitlab/gitlab.rb but the url is always wrong.

external_url “serverhost”

(Gitlab version 9.0.1)
