Hi Team
We are using simplybookme API to automate our business workflows. As such we are constantly using the refresh token API :POST [https://user-api-v2.simplybook.me/admin/auth/refresh-token](https://user-api-v2.simplybook.me/admin/auth/refresh-token) to update the token before using it to call other APIs such as getting booking details ([https://user-api-v2.simplybook.me/admin/bookings/](https://user-api-v2.simplybook.me/admin/bookings/)).
From today midday (AEST Time) the refresh token API is returning error as pasted below. Kindly requesting if I can be assisted on how can I get this issue resolved.

Hi,
it looks like you are trying to refresh token in multiple threads with the same refresh token, which cause the issue.
Please try to do it in single thread and let us know if you still have the issue.

Hi Dmytro
I stopped all threads and tried from a single one but it still does not work.
Please note that we normally get error 404 when the url does not point to a valid page.
Can you confirm if the url is same as [https://user-api-v2.simplybook.me/admin/auth/refresh-token](https://user-api-v2.simplybook.me/admin/auth/refresh-token) and that the page still exists ?
