tvos w/FTP: "SERVER CONNECTION FAILED" on first connection attempt

[sqw]

Hello,

I'm using the latest tvOS release on the app store, using the generic server connection with a local vanilla/active FTP. On first attempt to connect, I am always getting "SERVER CONNECTION FAILED". If I then retry, it connects right away and I get all expected behavior. Anyone else see the same result? I would be happy if it just silently retried at least once before giving the error!

Hello,

Would you be interested into testing our beta version in order to see if you reproduce the issue ?

Thanks

I have never been successful here, the connection has always "SERVER CONNECTION FAILED". Tried again and "SERVER CONNECTION FAILED"
