The solution I found is quiet simple, :wink:
I switched the cloud account from S3 to Open Stack and since than I have been able to upload even bigger files than the 8GB public folder database.

I have contacted the support team and they found out, that a timeout problem occurs during uploading the file. Therefore I think the reason is the default configuration of the Object Storage Server which based on Open Stack Swift.

Thank you for your help,
Florian

Thank you for the reply. I have just created a ticker, if we found a solution I will post it in this forum, because it might help others.
