Everything else, as far as I can tell, appears to be working correctly – just upload rendering that’s acting rather peculiar.
I’ve verified this behaviour on a completely fresh build – that is, `rm -rf /var/discourse`, completely nuking `docker`, and following cloud install + subfolder instructions.
If there’s further investigation I can pursue, I’m happy to take those steps. (sorry for imgur links – I’m not allowed 2+ image embeds here yet!)
Cheers!

Some extra info – looks like the src is already stripped away before rendering, as it is missing in the production database:

Tracked this issue down further to this function: [discourse/app/models/post.rb at main · discourse/discourse · GitHub](https://github.com/discourse/discourse/blob/main/app/models/post.rb#L300-L338)
Modified my local function:
```rb
def cook(raw, opts = {})
Rails.logger.info("Cooking post with raw: #{raw}")
# For some posts, for example those imported via RSS, we support raw HTML. In that
# case we can skip the rendering pipeline.
return raw if cook_method == Post.cook_methods[:raw_html]
options = opts.dup
options[:cook_method] = cook_method
post_user = self.user
options[:user_id] = post_user.id if post_user
options[:omit_nofollow] = true if omit_nofollow?
if self.with_secure_media?
each_upload_url do |url|
uri = URI.parse(url)
if FileHelper.is_supported_media?(File.basename(uri.path))
raw = raw.sub(
url, Rails.application.routes.url_for(
controller: "uploads", action: "show_secure", path: uri.path[1..-1], host: Discourse.current_hostname
)
)
end
end
end
cooked = post_analyzer.cook(raw, options)
Rails.logger.info("Cooked into: #{cooked}")
new_cooked = Plugin::Filter.apply(:after_post_cook, self, cooked)
if post_type == Post.types[:regular]
if new_cooked != cooked && new_cooked.blank?
Rails.logger.debug("Plugin is blanking out post: #{self.url}\nraw: #{raw}")
elsif new_cooked.blank?
Rails.logger.debug("Blank post detected post: #{self.url}\nraw: #{raw}")
end
end
Rails.logger.info("New cooked into: #{new_cooked}")
new_cooked
end
```

Managed to track post uploads down to this exact line:
[https://github.com/discourse/discourse/blob/main/app/assets/javascripts/pretty-text/addon/sanitizer.js#L23](https://github.com/discourse/discourse/blob/main/app/assets/javascripts/pretty-text/addon/sanitizer.js#L23)
in particular,
```js
// relative urls
if (/^\/[\w\.\-]+/i.test(href)) {
return href;
}
```
breaks because since my forum URL is being served out of an apache user-webdir (which I don’t have control over), it starts with a `~`, which breaks that regex.
I’ve confirmed that modifying the character class to include `~` (as `[\w\.\-~]`) fixes the post uploads, but painfully avatar uploads are still broken!

…aaand the other broken regex:

same ordeal – needs a `~` in the character class
which fixes my avatars

If Core is not so keen on a PR, you could probably permanently resolve that with a custom plugin for your specific site.
