Redmine

(Even when I click "repository")
By this I mean: I made a commit with the following message:

screenshot now button

fixes #5

But I go to issue 5 and there's no reference to the commit, the issue is still open, etc. Now I might think this was just a matter of not setting up the automatic fetching, but: even if I go to the repository for that project and view the commit, it doesn't link it. So thinking maybe that didn't work, I went to <my redmine url>/sys/fetch_changesets?key=<my redmine key>. I saw just a blank page. (I think that means it's working though, because when I took off the key I saw "access denied".)
I'm on bitnami redmine 3.3.0-1, if that helps.
