Tried with filezilla and smartFTP but cannot make a connection to my box. I have tried multiple pc's running win7 and win10 - I have been able to connect previously (about 1mth ago) but cannot connect now, I have disabled windows firewall, switched of my anti-virus and even disabled the firewall on my router but still cannot connect. My box is hard-wired to my router, but I am connecting by wifi from my laptops. Both laptops and vu duo box are connected to the web without any issue.
I get the following rejection messages...
Filezilla: Connection attempt failed with "ECONNREFUSED - Connection refused by server".
smartFTP: No connection could be made because the target machine actively refused it.

I have now run out of ideas, just wondering if anyone else has had a similar problem and fixed it? or if anyone can offer any further things to try?
