After generating new api key, cannot access terraform cloud

I’ve been using circle CI and TF cloud for a few months now. Despite generating a new key and setting the env var in my runner, I am getting:

│ Error: Failed to read organization "***********" at host
│   on line 3, in terraform:
│    3:     organization = "***********"
│ Encountered an unexpected error while reading the organization settings: unauthorized

And 4 days ago doing the same thing on another project was fine, but the current project doesn’t seem to even attempt to use the key I set in the env vars. It just shows:

Token has not been used

Is it possible there is a bug or is there something I’m missing this time round resetting the key after it reached its TTL?
