Transmission problem with OS 6

Do you have the latest version of Transmission App from http://apps.readynas.com/pages/?page_id=9 ?
Have you tried to uninstall/reinstall the Transmission App?
Have you tried using other browsers like Firefox or Safari?

Thanks for the answer.
I tryed all what you have suggested but nothing, always the same error message.
When I start transmission the system asking me for user and password and I enter admin/admin, is it correct?
The strange thing is that it was working before then I have deleted the volume to insert a new hard disk without RAID so now I have 2 disks (one 1TB and one 3TB), after this the trasmission application did not work anymore; any suggestion?

Have you tried using one of the Transmission Remote apps, available for Windows and Android, possibly Apple iOS too

Did you give the new volume the same name as the old one or a different one?

Different one.
The old was video, now I have Video1 and Video2

I tryed with the Android app but I don't know how to set up the account.
When I try to connect I receive the message "Unauthorized connection"

You probably need to stop Transmission and edit the Transmission configuration file to point to the share on the new volume rather than the old deleted one.

Do you know where I can find the configuration file and the file name to edit?

The settings are stored in /data/Transmission/config/settings.json

where 'data' (no quotes) is the volume name. Obviously if your volume name is different you need to use your volume name.
