Repository import get stuck on crendentials request

Hi folks, I’m trying to import an existing repository in my account to an organization but the import routine get stuck on the credentials:


I put the credentials, github try to do the import and then ask for the credentials again in an infinite loop.
I have all credentials on the imported repository and I currently working on the old repo. but I need to import the repo to the organization account to allow anthers work in.

thanks in advance
