  From about the time you wrote this, all outbound IPv6 connects are still  
  failing, but all outbound IPv4 connects area successful:

  Maybe your IPv6 changed?  
    
    
  Interface Identifier (The Device Portion):  
    
  The last 64 bits (0acb:a059:6e85:1ded) identify the specific interface.  
    
      Randomized/Privacy-Focused: Looking at the interface ID, it does not  
  follow the older EUI-64 format (which embeds a device's physical MAC  
  address into the IP using ff:fe). Instead, it is either statically assigned  
  by the server administrator or generated randomly using privacy extensions  
  (like RFC 4941 or RFC 7217). This is standard practice for modern operating  
  systems and security-focused networks to prevent device tracking.  
    
    
  Bye, Wilfred.
