We are sorry for your inconvenience. We have investigated the issue and found the root cause. It is not a bug in aspose.words cloud API but something in the AWS environment that effecting intermittently the API calls. We are working on it as high priority and will notify you as soon as it is resolved.

We are also getting this error. The UTC+02 timestamp it happened for us was 5/28/2019 04:13

Can we get an update on the fix for this problem?

Is this an exception that can get solved by retrying?

@rvanlaak

Thanks for your inquiry. Above error seems some network related issue. However, can you please share your error details(message). It will help us to identify whether it is same error or different.

We are sorry for your inconvenience.

We do not have more information, the error message is almost identical.

Can you give an update on the fix for the AWS problems mentioned on February 27?

@rvanlaak,

We had memory issues with big files and made some load balancing changes on the server. We are unable to notice this issue after this fix.

Furthermore, along with the load balancing update, we have also deployed a new fix to route requests larger than 5MB to another server for processing. So we are confident you will not face this issue again. Thanks for your understanding.

We did not see any more SQL server outputs in the logs on the last 100 conversion errors, so this seems resolved.
