I cannot log in my store from RUBY?

[CanadianDesign]

My store name is raccoondesign.myshopify.com/. When I log in to Ruby, I get this error. I also created a github and main is the main branch of my file. I did't linke the defaulth theme on github ,but another one. I did update Ruby to the last version and Shopify CLI is on there. I have version 3.. something on it

Please, can you help, I am desperate.

Thanks
