Some possibilities:

1. Account lockout due to too many sign-in failures. If this has happened you'll need to contact your provider to regain access
2. Temporary account lockout due to rate limiting. If you have too many sign in failures your account will be locked for some time period such as 1 hour. You can try again after the lockout expires. If this is your case you have probably already regained access by now

Hopefully, you're using a VPN to connect to your provider before trying to RDS into a computer on port 3389. That port should never be opened to the public internet; if it is, it will be subjected to continuous attacks which will need to be handled by that computer.
