I am afraid, webex session may not be an option because Aspose Support Forums are the best place to discuss technical issues in a controlled environment.
As discussed earlier, we cannot establish your recently presented scenario as a bug on the part of Aspose.Cells for .NET component. This is due to the reason that you are experiencing some problem (you haven’t shared the error details so far) while uploading a file to your server, whereas Aspose.Cells for .NET does not provide such feature. You must be using some .NET control(s) for uploading the files in your application. You can confirm this by removing/commenting all Aspose.Cells for .NET API calls from your application while leaving the code to upload the file intact. Deploy on your server and see how it goes. If you experience the same issue that means Aspose.Cells for .NET API has nothing to do with the error. Moreover, as you are able to execute the program on your local machine without experiencing any problem therefore we believe the problem could be more related to the configuration settings or access rights on the server. We can help you further in this regard, if you can provide the error message along with a sample application replicating the issue. Please note, you do not have to provide your actual application for our review. You can create a simplest, subset of your original application just to replicate the issue on our end. Along with a sample application we also require environment details such as,
- Operating System version (Windows Server 2003)
- Operating System Architecture (32 bit)
- Target Framework
- IIS version (in case you are deploying the application on IIS)
- Browser used to test the application
