[image] Configure an S3 compatible object storage provider for uploads AWS S3 What we officially support and use internally. @Falco I this still the case? I thought I read something about recent issues using AWS but I can’t find the topic again. I am having numerous using AWS S3 using the var…

Whew! It took a ton of time and some hours (8 over 2 calls) on the phone with a very helpful Amazon engineer but I think I have my head around this. Things are working great on the RepealOBBBA site and my process is reproducible to other sites. I may write things up but a few notes for now: DISCO…

After you change the settings you need to run the rant task to upload the the assets. Also, you can open the developer console and see if the files is trying to access exist on the bucket or if there’s an issue with the cdn

Thanks for continuing… Yes, rake tasks are run, makes no difference. ./launcher enter app rake posts:rebake rake uploads:migrate_to_s3 rake posts:rebake_uncooked_posts Throbber persists. rake uploads:migrate_to_s3 does yield an error Migrating uploads to S3 for 'default'... Some uploads were…

The assets are called from the cdn, but are they there? If not, are they in the bucket? Are they accessible from the bucket? You likely have some uploads in a different bucket or something that keeps them from being in the expected place. If so, you’ll need to fix those by hand like it sats. You’ll…

Yes they are there, files are in the bucket as assets Accessible: https://repeal-obbba-discuss-uploads.s3.us-east-1.amazonaws.com/assets/logo-815195ae.png Only two buckets, uploads and backups. Backups are working fine. rake s3:upload_assets gave error: rake aborted! Aws::S3::Errors::AccessCont…

It sounds like you fixed the bucket and it’s now able to upload assets, so the site should work now. Dealing with the uploads that won’t migrate is another (complicated) issue. Here’s one of the assets you’re trying to serve: https://discourse-cdn.repealobbba.org/assets/start-discourse-6f03a463.br…

[image] pfaffman: So you need to change your s3 CDN to https://repeal-obbba-discuss-uploads.s3.us-east-1.amazonaws.com – oh, I guess that’s the bucket address, so that wouldn’t be ideal, but it would work. Not to keen on “so that wouldn’t be ideal” :wink: Looking at AWS Alternate domain name…

[image] philh: @Falco I this still the case? Yes, all the sites we host use the S3 plus CloudFront combo. Even this site you are browsing right now.

Thanks for confirming! After seeing this I re-adjusted DISCOURSE_S3_CDN_URL: back to amazonassigned.cloudfront.net hoping it my clear the cert and url issues. [Screenshot 2025-12-11 133250] The rebuilt and re ran all the rakes mentioned in docs. rake posts:rebake rake uploads:migrate_to_s3 stil…

edit from above
Switched to ACLs enabled and ran s3:upload_assets edit: uploads:migrate_to_s3 again

Thanks again for your time on this!!
