Update S-Card firmware problem


I am facing this problem since morning. What’s the exact problem.
SigmaKey v.2.19.00
Detected GsmServer S-Card products:
S-Card: 804****** Sigma dongle, v 2.18
S-Card: 804****** Sigma dongle, v 2.18
cannot connect to the server,
check internet connection or try later
Wrong or incomplete server reply received

Is the problem in my PC/BOX or it’s server problem? 🙂
