Yext command is sending me to authentification page in yext.com and it doesnt recognize my user

Hi everyone

im trying to use “yext pages new” command to create the pages needed to finish the pages track.

when i run the command in my console it says that my credential have expired and i have to authorize again, suggesting a link to do it.

But this new screen under sandbox.yext.com with a long list of parameters doesnt recognize my user / password.

But im able to log in hitchhikers.yext.com

I dont know what is happening but i suspect may be the trial period for my user in the sandbox enviroment has ended.

Andy suggestion about how to solve this?

Thanks in advance.
