## Steps

1. Use the TokenHub base URL and your TokenHub key when going through Tencent MaaS, and set TOKENHUB_BASE_URL for a different region. Pick the regional host that matches your key.

## When to use

## When not to use

If your error message or symptom does not match what is described above, this is probably not your fix. Search for your exact error text instead of forcing this one to fit.

## Versions
