 Check your Internet connection and try again.

Hi Elsabe, 
 
The error might appear because your Antivirus is blocking the connection to Language Cloud. 
 
You should set Trados Studio in the list of exceptions for your Antivirus and also make sure that that Studio is installed with Administrator rights. 
Since each Antivirus is different I couldn't advise exactly how to set this exceptions, so it would be a good idea to contact the Technical Support of the Antivirus company. 
 
Firewall exception for URLs: 
 
lc-api.sdl.com 
languagecloud.sdl.com 
 cxc-languagecloud.sdl.com 
 
Also an exception for port 443 would be required to allow access to the Language Cloud servers. 
 
If the issue persists please log a ticket with LC Support as explained here:
