Upload of large files to Web server fails with ZTNA

Products

• Symantec ZTNA

Issue/Introduction

ZTNA setup with Web Application to an internal Web server.

Users can access this server via the ZTNA Portal and Cloud SWG integration via WSS Agent.

One user reported errors uploading large files - after multiple tests, anything over 1GB was found to fail. 

Downloading large files does not seem to be an issue.

Environment

ZTNA.

Web Application.

Cause

ZTNA has a 1GB limit on uploads to Web servers.

Resolution

ZTNA Engineering looking to see whether this limit can be increased.

Additional Information

The limit is not due to the retry mechanism implemented: in the scenario where one connector suddenly fails and another connector takes over, it will still be able to send the request up.
