I try to generate a new certificate but the problem remains. 
 But fortunately i found the solution, the problem is caused by defunction of the pattern updates, sometimes the pattern updates doesn't make download of the clients correctly. The client authentication, ssl client and others belongs to Base Firewall Licensing. So if pattern updates doesn't work, the download of the clients comes with 0 Bytes. 
 The solution is copying manually the client binaries of the Sophos that is working to the respective directories in Sophos with problem. In this case via advanced shell ssh in /content. 
 In this directory there are thw following files: 
 client_auth -> /content/client_auth_2.00/1.0.0003 ( Symbolical Link of the client authentication ) 
 client_auth_2.00 ( Folder, if the download is 0 Bytes, probably this folder is empty ) 
 sslvpn -> /content/sslvpn_1.00/1.0.005 ( Symbolical Link of the SSL client authentication ) 
 sslvpn_1.00 ( Folder, if the download is 0 Bytes, probably this folder is empty ) 
 
 The way to transfer files in sophos firewall can be learned here . 
 
 obs: The binaries must be in same directory path expressed in the respective symbolical link

I have seen that once you upgrade from cyberoam, sometime the certificate are not updated. Make sure to regenerate the CA (clicking on the gear) and then regenerate the SSL appliance certificate. 
 Once the certificate has been regenerated, download the SSL client.
