Assets thumbnails not loading on Publish

[mozzvinod]

Hi All,

I am facing this weird issue of images not loading on the publish server, while its working good on Author. I have configured below on the publish dispatcher with n success at present:

Could you please help and highlight the missing part if any.

hi @mozzvinod can you set the dispatcher level to debug? When you monitor the logs do you see the dispatcher rejecting the image requests?

At a minimum you will need to open up the /content path and allow some of the mimetype extensions:

/0023 { /type "allow" /url "/content*" }
/0041
   {
        /type "allow"
        /extension '(clientlibs|css|gif|ico|js|png|swf|jpe?g|woff2?|mp4|mpv|avi)'
    }

If you're running Dispatcher 4.2+ you can use trace level logging to identify exactly which rule is being applied to the denied request.

Thanks the issue was around thumbnails and was resolved by allowing path url from "content/dam/projectname". Thanks once again for the help.

What version of ASC?

Can you access them directly via AEM Publish? And/or does this only break when accessing ASC via Dispatcher?

A simple check would be to, using the same login session, used for the ASC site, make a direct request to the asset under /content/dam/projectname via AEM Publish hostname, and then via Dispatcher hostname. If you cannot access the asset direct via AEM Publish, you have an issue in AEM (likely ACLs or Asset rendition doesn't exist?). If it works when accessing direct to AEM Publish but NOT via AEM Dispatcher, then you have a Dispatcher config issue, likely an issue with your allow/deny filters.

Hi David, Version of ASC is 1.8.0.

The issue is cropping up on publish only now. Renditions exist (all works good on author) but still not loading. I am accessing publish using admin user. What ACL right I need to take care of here.

Regards, Vinod

@mozzvinod does it work if you access AEM Publish direct (on port 4503) or only when you access via Dispatcher?
