I greet this great community. I managed to install DSM in version 6.2.3-25426, everything seems to work reliably and without problems. The only problem I discovered is that the Download manager does not work. I have a prepaid credit at "uloz.to". The original DSM plug-in for "uloz.to" verifies my login details and they are fine, but cannot download. I will download, save, add to the system the recommended plug-in from the company "uloz.to", but the verification of my login data says that it is invalid, even though I am sure that the data is 100% correct. Do you have any solution or idea, please? I have spent a lot of time on it and without success. And even about 1 month ago before my real synology DS412 + broke this worked. Thank you all for the rare advice. Lucas
