Gitlab runner can no longer clone

Since reconfiguring the external_url for gitlab, and validation user access, i had to reboot the server to unlock docker who was eating cpu.

but since the reboot, the registry went empty (dunno why), and i tried to rebuild projects to populate the registry.

but when i build project, the runner user the intender token, but get a 403 unauthorized on git clone.

Cloning repository…
Cloning into ‘/builds/wiidii/tool/corellia’…
remote: You are not allowed to download code from this project.
fatal: unable to access ‘’: The requested URL returned error: 403

I tcpdumped the connection, and validated the token who was intended for this use as ok.

we have gitlab behind a haproxy whos is https, and query the gitlab in http (without ssl).

Do you have any clue about this problem ?
