Aspose Email Stops Reading Mails From Inbox Post throwing request timed out WebException. This issue happens only in AWS Windows/ Linux environment .

Following code snippet to get the connection

NetworkCredential credentials = new NetworkCredential(userName, password, “”);
String mailboxUri = “https://outlook.office365.com/ews/exchange.asmx”;
IEWSClient client = EWSClient.getEWSClient(mailboxUri, credentials);

@anand_bhavi_arisglobal_com,

Thank you for contacting Aspose Support.

We were unable to reproduce the issue on Linux using the latest version of Aspose.Email for Java API. It is requested that you try connecting from a different network. If possible, please share the test account credential so that we can investigate this scenario further. The screenshot of the result is also attached for your reference.

Hi ahmad,

The issue doesn’t occur in normal Windows/Linux setup. It happen’s only in AWS Windows/Linux set up that too post 4 - 5 hours . Up to 4 - 5 hour’s system will be able to connect to inbox and read the mails. Once we restart the our application then again it’s works up to 4- 5 hours.

Since connection is established through web services , is there any settings suggested for AWS environment to work seamlessly without re-start of our application.

muhammadahmad · 2018-12-10 14:46:02 UTC

@anand_bhavi_arisglobal_com,

Thank you for your feedback.

Our API does not provide any environment specific settings. As long as the environment is compatible, the same code should work. Additionally, the request timed out exception is a very generic which can arise due to a variety of reasons.
If possible, please provide the details given below so that we can investigate the scenario further.

Please let me know is there any manual ways to identify whether the request time out is occurring while retrieving WSLD file or authenticating credentials.

muhammadahmad · 2018-12-11 14:33:47 UTC

@anand_bhavi_arisglobal_com,

Thank you for your feedback.

By reviewing the stack trace that you shared, we observed that you were using an older version of Aspose.Email API whereas, it is always recommended to use the latest version of the API because it contains the latest enhancements and features.

By looking at the stack trace, it seems that the issue is related to authentication however, we cannot share additional details unless we are able to replicate the issue in our environment using the latest version of the API. Please test this scenario using Aspose.Email for Java 18.11 and in case the issue persists, please share the respective stack trace.

anand_bhavi_arisglobal_com · 2018-12-12 05:14:21 UTC
