[Smush Pro] Throwing 503 for images

We have a problem on our site with Smush CDN. The images are not showing up and they return a 503 error. If you open the direct address of any image, they return the following error:

Error 503 Backend fetch failed

Backend fetch failed

Varnish cache server

The site is hosted with WPMU DEV hosting and we don’t have any caching plugins on the site. Please advise.

    Hello Lucian Iordache

    This was happening, and I’m saying “was” cause images are being displayed successfully in the staging site now, because of a 24hrs caching in our CDN in combination with the recent migration of the site into our hosting service which triggered it.

    As the 24hrs have passed, you can see that staging looks good now, so feel free to enable in the live site as well.

    Please keep in mind that this is already reported to our developers who are examining ways to surpass it via the CDN service itself.

    Thank you,
    Dimitris
