Another observation: I just noticed when I upload a new avatar, the image does successfully upload to s3. I can inspect element prior to saving and see that the url is a s3 (via cdn) url and it works fine. After I save however, all references to the avatar are for a local image (which also works).
@markersocial your avatar uploads are still serving from the S3 storage only. The local URL which appears in the UI is a dynamic proxy URL which used to serve the avatars in many custom sizes.
Thanks @vinothkannans, appreciate it! Really good to know.
I did notice though, when I inspect avatars in a thread on meta.discourse.org I see a cdn url. When I do the same on the other forum (that has a cdn configured for s3), I get a local url. Not sure if that’s a concern.
