Some pictures don't display after a domain change

AI-generated summary

User thaidb reports that after changing their Discourse domain following the guide at Change the Domain Name or Rename Your Discourse, some post images fail to display — though new posts show images correctly. Rebuilding HTML for affected topics does not resolve the issue thaidb. pfaffman asks if new posts display uploads properly — confirmed yes thaidb — and whether Sidekiq has pending rebuilds; thaidb shares a screenshot showing no backlog. pfaffman then asks if images are stored locally (not S3) and if a CDN might be misconfigured; thaidb clarifies they don’t use a CDN, only manage DNS via Cloudflare, and asks what S3 is. The core issue remains: old topic images are missing post-domain change, despite correct rebuilds and no CDN or S3 in use. Further diagnostics may involve checking upload paths, asset URLs in the database, or Cloudflare caching rules.

If you look at /sidekiq do you see a bunch of rebuilds still waiting to be processed?

The images are on local storage and not S3?

Do you have cdn that’s not pointing to the new domain?

I don’t use cdn service, i only manager domain by Cloudflare.
