EXTREMELY IMPORTANT: Please attach a ZIP file containing your Akeeba Backup log file in order for us to help you with any backup or restoration issue. If the file is over 2Mb, please upload it on your server and post a link to it.

Description of my issue:
On my local host I'm able to get the backup files in my dropbox.
From my live site not. My first mistake was that I did a reconnect.
Today I removed the access from Dropbox and created a new one via my live site (poawer.nl)
Backup procedures created 3 files (max size 7 Mb), then not able to put the files on dropbox error 400.

Kind regards,

Hi Wil,

It looks like your host kills the connection to Dropbox after two seconds. You can try a workaround to that. Go to Akeeba Backup's Configuration page and find the Archiver Engine. Click on the Configure button next to it. In the pane which open below set the "Part size for split archives" to 5 Mb and save the configuration. The backup will now consist of four files (.jpa, .j01, .j02 and .j03) and they should be transferred to Dropbox successfully.

I tried it with the 5Mb archive files and even with the 2Mb files.
In both cases error 400.
IWill this than also happen if I go for example to Amazon?

I suspect that this is a server firewall issue. Since both Dropbox and Amazon S3 share the same server (Dropbox uses Amazon EC2 and S3 for its infrastructure) I assume you will have the same results. I'd recommend asking your host to confirm if there is a server-side firewall disabling this kind of communication with external services.

Nicholas,
They find it difficult to determine if it is a firewall restriction from their site (translating it from Dutch). They made some changes to the php.ini
- increased the php memory limit to 32MB
- increased the post and update size
They stated that if this will not help have a look at the error_log file. But the actions of yesterday and today are not in the error log file. (Did ask them why)
On jun 5 I found in the error log file
-------------
[Tue Jun 05 15:43:09 2012] [error] [client 82.171.42.163] PHP Notice: Undefined variable: res in /var/www/html/administrator/components/com_akeeba/akeeba/plugins/engines/proc/dropbox.php on line 113, referer: http://www.poawer.nl/administrator/index.php?option=com_akeeba&view=config

I saw also that the file rights are not the same for all created backup files.

Hm, 32Mb is very low, but this is not relevant since the backup does complete. The notice is also inconsequential. I still think that there is a communications problem between your site's server and Dropbox.
