Group link broken

Hello,

I just finished setting up a fresh gitlab-ce setup but I still got a problem with the group link. I mean, when I click on a group name in the groups list, I’m redirected to “http://git-1.ip-91-121-135.eu/groups/test” if group name is test (for example). This domain is invalid and do not correspond with the domain I’m accessing gitlab which is “http//git.simple-duino.com:8888”

I don’t really understand what the problem is…

Thank you for your future help
