Hi, Firstly, congratulation for this open source project. I want make clean display for local pdf files with onebox. I saw that is not to possible with attachment, so i link pdf files from url on same server. With or without whitelist internal hosts, That work with domains but i don’t see onebox for pdf files from subdomains url (my discourse url is on a subdomain). For my tests, All domains/subdomains redirect on the same server. [discourse] (On test screen, only domains display onebox) I have read some posts about this, but i don’t understand the problem : [image] Internal URL no longer oneboxing Support At some point in the last 2 days internal URLs stopped oneboxing on my instance. I’m up to date with tests-passed as of 1:15 AM EST 6/9/17. There are the errors I’m seeing in the console when a post with an internal URL is loaded. There do not appear to be any related errors in /logs. [image] https://meta.discourse.org/t/onebox-domains-whitelist-and-subdomains/40884 How i can fix it ? Thanks, PS : Link work for subdomain, i can see pdf file, that’s just display problem for onebox on content.

I have search in the code, def self.external_onebox(url) Rails.cache.fetch(onebox_cache_key(url), expires_in: 1.day) do fd = FinalDestination.new(url, ignore_redirects: ignore_redirects, ignore_hostnames: blacklisted_domains, force_get_hosts: force_get_hosts) uri = fd.resolve return blank_onebox if uri.blank? || blacklisted_domains.map { |hostname| uri.hostname.match?(hostname) }.any? options = { cache: {}, max_width: 695, sanitize_config: Sanitize::Config::DISCOURSE_ONEBOX } options[:cookie] = fd.cookie if fd.cookie if Rails.env.development? && SiteSetting.port.to_i > 0 Onebox.options = { allowed_ports: [80, 443, SiteSetting.port.to_i] } end r = Onebox.preview(uri.to_s, options) { onebox: r.to_s, preview: r&.placeholder_html.to_s } end I think the problem is here, no mention for the whitelist ? return blank_onebox if uri.blank? || blacklisted_domains.map { |hostname| uri.hostname.match?(hostname) }.any? pdf.pdf 423.82 KB This link don’t work too, https can be is the problem ? Thanks,

Finally, the subdomain without https is the problem.
