Filezilla ftp access denied

Hi? I have configured FILEZILLA to access to our ftp but we keep getting this message:

Status: Access denied
Error: Authentication failed.
Error: Critical error: Could not connect to server

It is this a temporary denial of the access by dreamhost servers? or is it a mistake on my part when setting up Filezilla?

Your kind advice would be appreciated.

If it’s a temporary block, the help page suggests contacting support to get it removed:

https://help.dreamhost.com/hc/en-us/articles/115000675027-FTP-overview-and-credentials#ip_blocks

If you make several unsuccessful attempts to connect via FTP using incorrect credentials, an automatic block will result. This is a security measure.

As habilis suggested, a DH admin will need to unblock this for you.
