Hello everybody, I'm also experiencing the "retry in 15 minutes" issue.
It seems that the download struggles to start by jumping from connected to disconnected etc a lot and then fail to this error. If the download starts correctly, there is no error.
If the error occurs, I can reset the file and it will try again to download
Btw, I've a second computer, connected to the same network and I have the same problem on it.
I read this thread and I was wondering if there is a known solution about it ?
Thanks in advance !
