No route for /v1/images

Hi all,

When I want to list glance images (with CLI or horizon dashboard), glance failed telling that there is no route for the request.
Extract from glance-api.log :

It works few days ago, I didn't change config since, only recheck code from github with devstack.
I reset 2 times :
- first running devstack again,
- second, all from scratch.
Also reboot the server. No changes.

Anyone got ideas why it failed ?
Thanks
