turbobit not working with proxy

Error message: ERROR - File name not found
frd 0.86u1
plugin: 1.3.19

I can download the link with the default connection, but not though the proxy. Is turbobit blocking it? If so, could you please put a better error message other than "File name not found"?

Thanks!

There's no TurboBit error in the log, only a socket timeout on plugin update check.
