License issue

My colleague and me are facing issues with the license server. On Friday everything was ok. Is this a known problem? 

"An unexpected error occurred. The server failed to provide you with the TestComplete license.

Failed to connect to http://44.174.8.103:40892. A connection with the server could not be established. 

Probably, you do not have the Internet connection, the parameters of the secure Internet connection are incorrectly configured, or the SmartBear license server is not available."
