Letter avatar images are broken

Users without custom avatar images have broken avatars. Trying to navigate to the images gives a 404; for example: https://discuss.ipfs.tech/letter_avatar_proxy/v2/letter/s/f1d935/90.png.

Is an admin able to fix this? This seems to be the same issue as this thread (see for fix instructions).

I am experiencing this as well

Does @admins contain someone with access to the IPFS discourse server?

Someone seems to have fixed this. Thanks to whomever did!
