I need to login several times

Using the latest Chrome under Windows 7, I login correctly on GitLab (I see my name in the righmost dropdown menu) but every page I change - i.e. the repository optionson the left, commits, any file in the repo, etc… - I come back to the login page and I have to enter again the credentials. Every time the login ends successfully (and I see the page I’ve clicked before) but again a new link leads to another login.

After 3-4 (or even 5) logins, suddenly I can navigate without any other problems.
I allow cookies and I don’t have any web anti-virus/malware.

It’s a known behavior?
