Why my GitLab instance is resolving to 127.0.0.1:8082

This issue is a question issue.

I would like to know what is wrong in my GitLab instance because it is resolving to 127.0.0.1:8082 in some points.

It appears when I click in ‘Your work’, New navigation and when I resolve conflicts.

Have someone a idea that why it is happening and what setting I have to change to solve this?
