docker compose up -> 401 Unauthorized

I was trying to set up a new retool instance on docker when I encountered a 401 Unauthorized error:

$ docker compose up -d
[+] Running 3/3

I had just signed up for a new docker account and had not verified my email yet. Docker will return 401 Unauthorized if your email is not verified.

I’ve hit this issue a few times before, always after starting a new job. Quite frustrating!
