Please remember that this is a public forum, meaning that anything you publish here is visible to everyone. So make sure to not share any sensitive data here, such as passwords.
I have reset your hosting account password and re-listed the topic. You can find your new hosting account password in the client area. You may still want to check your account for anything unusual, because it’s possible the password may have been seen by others before it could be reset and removed.
Feel free to update the password through the client area if you want, but do not set it to your previous password.
As for your question itself, the “Access denied for user” error is listed in this article. Maybe the information there can help you?
