Session termination/auto log-out upon file upload completion in File Manager

As per the title, often when i upload a file to our ‘File Manager’ area, i will be instantly logged out and returned to the main login page.

There doesn’t seem to be any pattern in regards to file size, with ranges from a few KB to 20-30MB, usually PDFs or Word documents.

Steps to reproduce

• Log in to the application.

• Navigate to File Manager via the left-hand side pane.

• Open any sub-folder.

• Click Upload File, select a file, and click Open/Upload.

• Observe the page behavior once the upload finishes.

• Uploads are always successful despite this behaviour
