Every time an admin tries to log in, he/she receives an error that the "User Name or Password is Invalid". The admin then goes through the password reset process and is able to log in.
This behavior usually indicates that you have a saved shortcut or bookmark to the incorrect URL, which is why the URL in the password reset email works, but yours doesn't. If another colleague is able to log in, try using the same URL that they do and update any saved shortcuts or bookmarks that you may have on your computer. You can also try using this to locate the URL: Luminate administrator login URL. You can find your shortname in the URL of your password reset email.
Alternatively, you can Contact Support and reference this article. Support can provide you with the correct URL to log in.
