Evalai push image problem

Hi, i am Host Code upload based challenge.
Last year, the evaluation challenge was held and operated.
An error occurred while testing to hold the challenge again this year.
The error occurred in the process of submitting the answer through evalai-CLI.
After evalai login, an error occurred in the process of evai push image.
The command is ‘evalai push agent:latest --phase the-phase_#-##’
The error message is ‘no basic auth credentials’.
To guess the cause of the problem, it may be the expiration of the Kubernetes token. However, I don’t remember how to set up the token.
I want to know why this error occurred and how to solve it.
Please help, Thank U!
