Thank you for your log file. Can you try the below and see if that helps?

1) Close all Xara programs. (Important! the changes won't be made or have any affect on the program if it is open, and values would be overwritten when you close it.)

2) Go to Start > Run and type regedit then click OK.

3) Navigate to the registry key for the version of program you are using:

64bit: HKEY_CURRENT_USER\SOFTWARE\Xara\WebDesignerPremium x64\16\Options\FTPLibcURL

4) Change the value ConnectTimeout, LoginTimeout and ResponseTimeout to "20000" (this is the time in miliseconds, so this would be 20 seconds).

5) Close the registry and open Xara

Does the problem now appear?

Thanks
Rob
