Im having the same problem since yesterday, did you fixed it?
it can´t check for updates and it can´t translate since it fails to connect with the server.

UPDATE: I manage to fix it and I will leave this here to help anyone that has the same problem, it had to do with my firewall (its not windows firewall but a paid one), it blocked the program, since I had problems in the past I used the "Optimize network" now I removed it by "Cancel optimization network" so the firewall asked me if I want to allow the program to connect to the internet, the thing is that it marks it as a java program .js and the name is nwjs so if you have a firewall and it asks for permision of that "nwjs.js" just allow it and it will fix the problem.
