Troubleshooting 401 Unauthorized Error When Connecting to Trial Region from the UK in WK Quickstart

Anyone had challenges connecting from wk to the trial region when connecting from the UK? I'm just giving the quickstart a go. I've followed the instructions for creating the client role and API client, copied the token, but I get a 401 error.

Error: validating token via /users/me: API error 401: Unauthorized A 401 here usually means one of: - wrong region: a valid token for a different region than "trial" fails against its base URL — re-run and select the matching region, or pass --base-url - expired or insufficiently scoped token - token truncated on paste

I've tried running wk auth login --region trial in interactive mode, as well as pasting in the token with the --token flag. I also tried explicitly setting --base-url. In any case. If anyone has any thoughts to share, I'd much appreciate it.
