Here's the link to my profile picture which is set as my avatar. Unfortunately, this does not match the link displayed in the post you provided. This means that the links being displayed on Amethyst are different than the actual links.

If you looked through Primal, you would see your issue with media not being displayed disappear.  

 FYI: Your profile pic is displaying now. I have not updated Amethyst or rebooted anything. The media link is also now viewable through Vanadium as they usually are. 

 It seems whatever issue Primal was having with their servers has now been resolved. All primal accounts have visible media again.
