    "Request is being processed, please try again later #1204" endlessly

    Jeff S · 6 · Last reply by Jeff S

    I'm getting the #1204 error for a large number of links and it doesn't seem to be going away, no matter how many times I reload. Unfortunately I can't share the links (private data) but they are being hosted by Google Cloud Storage. The original files are less than 1MB (although they're high res, 5400x4500).

    How do I kill all versions, sizes, transforms, etc of a file from cache?

    Field Agent · 5 · Last reply by Pedro Verruma

    How do I kill all versions, sizes, transforms, etc of a file? If a user rotates a photo, I update the file with the new rotated version. But when I ask rethumb for a thumbnail that was made prior to the rotation, I get the unrotated version. I see where I can send a version number in the URL to force rethumb to regen that specific request, but if I've got 10 different sized thumbnails, it becomes cumbersome for me to make sure they all get killed and regenerated. Can I kill them all at once so the next time

    Larry Lewinsohn · 0 · Posted

    What should be done about it? How long should I wait before trying again? Generic error has been there for hours in some sizes of some images.

    All Non-cached images seems to be responding with an error!

    Igor Escobar · 0 · Posted


    I'm evaluating the use of Rethumb on our services and seems like since today all "non-cached" images are not being created.

    This image for example:

    I don't see a reason why it isn't being generated.

    But this one, created yesterday:

    It is working fine (Cloudflare cache I think).

  • Custom domains support HTTPS?

    Pedro Verruma · 0 · Posted

    Yes, when you active a custom domain on our dashboard we create a free Let's Encrypt certificate with no additional cost.

    These certificates are valid for 3 months but we handle all the necessary steps to keep it going while you keep your domain with us.

    This can be useful if you want to refer your custom domain name directly from another HTTPS site and want to avoid browser notifications about insecure content.

  • How the integration with CloudFlare works?

    Pedro Verruma · 0 · Posted

    CloudFlare stands between your user browser and our own servers. When a user requests an image for the first time CloudFlare passes the request to us. We then process the image and return the final image. CloudFlare will cache this image and subsequent requests won’t hit our servers (being served by CloudFlare alone). Virtually 100% of our requests are cache hits so this will bring a significative speed-up for our final users.

    We are also better protected against DDoS attacks and even when our all servers are down we can operate on some level.

    Note: clients using CNAME records won’t

  • There is support for custom domain names?

    Pedro Verruma · 4 · Last reply by Field Agent

    rethumb supports the use of CNAME records for custom domain names.

    You just add a CNAME record on your side with the value "" and use our dashboard to register the desired domain name.

    In this way you can use something like to access our api: will work just like

  • How rethumb works?

    Pedro Verruma · 0 · Posted

    rethumb is a image processing HTTP API, we accept image transformation or information requests, cached them and send the response as fast as possible.

    Lets check an example to see how things work.

    Start with an image that you want to process: By accessing our API you will be able to create thumbnails: etc. On the first time we will download the original image, process it and save the result. When someone access the API URL for the second time the response is already cached and ready to go. All our API works in this way and the kept the

  • How paid plans work?

    Pedro Verruma · 0 · Posted

    Your account starts in a free plan, at any moment you can subscribe to a paid plan for one year. These plans allow you to use special features for one year, after that you can manually renew your subscription or it will be move to a free plan.

  • What happens when my plan ends?

    Pedro Verruma · 0 · Posted

    When a plan subscription ends you won't be able to process new thumbnails using specific features of that plan and your account will move to a free plan.

    All thumbnails created before are kept until their expiration date is reach.

  • What happens when a thumbnail expires?

    Pedro Verruma · 0 · Posted

    When a thumbnail expires it will be removed from our system. But if the URL is requested again a new thumbnail will be generated and the expiration date will be reseted.


    Today you create a thumbnail by sending this request using the free plan: After 6 months that thumbnail will be deleted. But if you access it again a new thumbnail will be generated (just like the first one). 

  • Are thumbnails online forever?

    Pedro Verruma · 0 · Posted

    Each plan have different expiration dates for thumbnails. Thumbnails generated using a free plan expire after 6 months, but the ones generated using a Business plan are online for 1 year.

    Check expiration dates here:

  • What to do when the API returns an error?

  • I have a paid plan, what is a source?

    Pedro Verruma · 0 · Posted

    After subscribing to a paid plan you have to add a source. Only images hosted on those sources are processed using the plan features.


    I subscribed to a Pro plan that allows me to process images with 6 MB in size. My images are online at, so I register "" in the dashboard to be able to process the images hosted at that domain. In this way I can process a large image (E.G.: 5 MB, that the free plan won't allow.

    By entering the domain "" as a source to use paid features all subdomains are automatically accepted as well:

  • Are there any bandwidth or request limits?

    Pedro Verruma · 0 · Posted

    The don't have any limits on bandwidth or requests for paid plans. Our free plan doesn't have hard limits but please don't abuse and keep usage in sane levels. You can create a lot of thumbnails and make millions of requests. Just don't create millions of thumbnails in a short time period.

    If you want more details on this please contact us at
