UnsupportedApiVersion - The Http resource ... does not support API version 1.1

Can you please advise on this problem we are experiencing asap?
This is business critical.


The HTTP resource that matches the request URI [http://api.aspose.com/v1.1/storage/file/ActCert_Template.80ad14f0-dbe0-4496-b179-3d29d8680efe.doc?appSID=628c914d-34c4-43d1-a037-7569e5cbc271&signature=z1RxsDBFGwqKcvb9IN4E6fs1j4E does not support the API version ‘1.1’.

The problem seems to be with downloading the file.
i.e. this command:

A “temporary halt” of more than 7 hours?
Is it possible for us to receive some sort of notice of when your backend service will be down please?

Hi Mari,

The service itself was not down during this time: http://stats.pingdom.com/57j0mt2bv3es/1042767. This issue was caused due to a broken API and was mostly related to the Storage API. This is now fixed. However, I’ll discuss with concerned team to make sure all the customers are informed/updated proactively in case of any such breakage etc.

Please try it now and let us know if you still find any such issues. Hopefully, it should be working fine now.
