Hey there, 
  
since i had some trouble with the update, apex broke down once. 
so now this error (Update Check: Could not connect to the update server) is always coming up and i cant connect to any hub. 
  
i already reinstalled apex (new 1.15.13 and older.1.15.12 version) and checked all the settings. 
  
Would be lovely if someone could help me. 
  
Thanks
