failed connection

Any Ideas why the program will no longer connect, not sure if by the install of a security certificate on the server means I need to change the protocol?
error shown below -
[21:54:33] 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.
[21:54:33] Client closed the connection.

Double checked the Password and log on and seems Ok
Any suggestions welcome!

Please post the complete log.

Ok - will do

Add SmartFTP to the exceptions in your software firewall and antivirus product settings.

thanks tried that - it was in place, have removed and re installed the rule - but no luck still the same

Try to uninstall/disable your software firewall and antivirus product. As long as you are unable to connect, SmartFTP is being blocked.

Thanks - think the problem is with the server - I have been able to conect to anoth server via SmartFTP - so guess it's one for the hosting company
