I have website with 5 customer test accounts. REST API calls have been working for a while now w/o a problem.
Today, one customer account cannot get the customer token via REST API call (API response 401: "You did not sign in correctly or your account is temporarily disabled."), the other 4 accounts have no problems.
In the Mage 2 admin, zero accounts are locked. The account in question also shows as UNLOCKED in the account details. In the db > customer_entity table, the related account record has failure_nums = 0, lock_expires = null - same as all other accounts that work. We reset the password for the account, still the API does not authenticate this account.
Using the web front-end log in, the account does log in using the same email/pw used in the API call.
Any idea what is going on here with this one problematic account ?
This is a test environment, so not critical atm, but do not want to run into this in production.
