I installed confluence server 6.15.4, few handfull spaces. Things went well, and tried taking full backup, which fails.
With attachment, it fails, with error:
Proxy Error
The proxy server received an invalid response from an upstream server.
The proxy server could not handle the request GET /confluence/admin/dobackup.action.
Reason: Error reading from remote server

The XMLExport is generated and looks valid, as was able to import in development server.

If I disable attachment, it works. with attachment, size is only 1.6 GB, and without attachments - 1.2 MB. Issue is not with downloads, as backup is in temp folder, and it takes about 60 sec for exception. Seems some timeout value need to be changed.
Need this as pre-requirement for upgrades.
thanks.
