An established connection...

I used to be able to get into this ftp but since 3 days ago i keep getting this:

Resolving host name ftp.y-hosting.net...
Connecting to (ftp.y-hosting.net) -> IP: 66.98.170.21 PORT: 21
Connected to (ftp.y-hosting.net) -> Time = 0ms
Socket connected waiting for login sequence.
An established connection was aborted by the software in your host machine.
Cannot login waiting to retry (30s)...



after i disabled my firewall i got this

Resolving host name ftp.y-hosting.net...
Connecting to (ftp.y-hosting.net) -> IP: 66.98.170.21 PORT: 21
A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.
Cannot login waiting to retry (30s)...

Help me please.

I'm getting this message:
