Redirection when loggin to Studio

Hello dear i am installing a new openedx environnement but have a problem with authentification on studio .
If i login it redirects me in this link ‘http://edx.devstack.lms:18000/register?next=http%3A%2F%2Flocalhost%3A18010%2F
I have seen the setting env.json file but problem persist .
Thanks in advance

Hi,

You need edit this files /edx/etc/lms.yml or studio.yml in site_name

I am sorry but I didn’t find site_name in studio.yml file.
