FTPS suddenly stopped working

Hi,

I have been using ftps implicit connection over port 990 to deploy to our server, but in the last couple days it stopped working.  I got the error message "Connection to domain.com failed.  Could not connect to FTP Server on domain.com".  I have tried rebooting and re-creating the ftp profile, but that didn't help.  I am able to connect with the same ftps setting using two other ftp clients, so there is probably no problem with the server.  I am also able to connect using plain ftp on port 21.  There has not been any software updates.  Only unusual thing is that I was travelling and connected to a hotel's wifi.   Can't remember if I used the ftp to connect (don't think so), but certainly since I got back I have not been able to connect.

Any help is appreciated.  Thank you.

ps.  I am running Idea 13.1.4 with Java 7.  I have tried the following command without any success.

netsh advfirewall set global StatefulFtp disable
