Summary
Know why "Unable to save the application. Check the network connection, and try again” error prompts when uploading applications with 30 MB or greater file size in Mobile Security (TMMS) for Enterprise.
Details
The issue is caused by the default settings in the product and Internet Information Services (IIS).
By default, the IIS website where the product is hosted has a file upload limit of only 30 MB. On the other hand, OfficeScan has a maximum upload size of 5 MB.
To resolve the issue:
- Open the IIS Manager.
- Expand Sites and select MDM Web Site.
- On the main window of IIS, double-click Request Filtering.
- On the Actions Pane, click Edit Feature Settings.
- On the Edit Feature Settings page, go to Request Limits > Maximum allowed content length (Bytes) and change the value from 30000000 to a higher value. For example, 524288000 = 500 MB.
- Restart the IIS Admin service and World Wide Web Publishing service.
- Log in to the TMMS console and upload your application again.
