Unable to upload files more than 2GB in Plesk File Manager or Backup Manager: 404.13 Not Found

Symptoms

Cannot upload large file using Backup Manager or File Manager:

HTTP Error 404.13 - Not Found
 The request filtering module is configured to deny a request that exceeds the request content length.

Cause

Content-Length header of the request is larger than the value specified for this header in
maxAllowedContentLengthproperty in
ApplicationHost.config.

By default, maxAllowedContentLength value in Plesk is 30000000.

Resolution

Note: if you don’t have administrative access to Plesk server via RDP, contact your hosting provider regarding the issue

1. Login to Plesk server via RDP
2. Increase maxAllowedContentLength value:

   C:> %windir%system32inetsrvappcmd set config “PleskControlPanel/” -section:requestFiltering -requestLimits.maxAllowedContentLength:4294967295

   maxAllowedContentLength will be set to 4GB. This is the maximum file size which can be uploaded  through IIS. 

For files more than 4GB

Upload them using the other service (for example, FTP).

Local backup files can be imported to Plesk backup repository like this:

C:> “%plesk_bin%pmm-ras.exe” –import-file-as-dump –dump-file-specification=”C:backup.file”
