MickRutherford: GoG is reporting that "You're offline. Some parts of the application may be unavailable. Connect now" which seems to be preventing any update to 5.6.x for me. I'm stuck on Worlds Part 2.  
 There's no update available for me and If I try to verify /repair the installation, I get an "Update Failed E3 Failed to connect to GOG servers".  
 I checked my firewall and AV logs and no NMS or GOG restrictions exist or are being shown in logs. I have even disabled my AV and Firewall but the issue persists. Everything else seems fine - network comms are good.  
 Any advice? Is this something to do with GOG comms from the UK or is there something else to consider? Can I grab the update executable or trigger the download from within the binaries (doesn't seem so). Is there a GOG update server I can ping to double-check the comms status from here? 
  Servers from both GOG and Hello Games are needed and at least right now the GOG servers are down. I can tell because when I open Galaxy the is a note in the lower right that says "it looks like we were unable to connect to the service at this time."  
 The discovery servers on the Hello Games side are frequently overloaded, especially after a new version is released which attracts an excessive number of button mashers. You can see this with the spinning wheels at early screens or in the lower left corner of the Discoveries tab when in game. Right now the discovery servers are accessible. When these are down everything will show as not having been discovered yet and some other things do not appear such as the daily missions at the console in the Nexus.
