EasySync - unable to connect

[AndrewStrang]

I have set up and had sync working with one file on my server, however I have now changed the hosted file, set everything up the same and am getting an error of Unable to connect to server.  Could this be a security issue with the second file. 

Filemaker go and my desktop can both connect and open both files with no issue.

I hope someone can help me with this,  many thanks in advance.

Is the security identical for hosted / mobile?
