Error 3253 when downloading anything

Having the same problem here in Berlin, Germany. I'm using a Time Capsule, which is connecting to the internet through PPPoE and a VDSL modem. Haven't had problems before but ever since the latest update (I guess) I'm getting this issue and nothing so far has helped.

I've been having the same issue. One thing I found that helped me was to go into my internet settings and disable my proxy server. I noticed it would reset with each download but I was able to download without the error. Might help some of you.

It turned out in my case that my memory on my hard disk was running low, around 5 GB. I was getting the same error message of reset network connection etc. and no memory low error so didn't think to check it. I cleared off 20 GB of data and now the movie seems to be downloading fine (at least I'm up to 1.83 out of 4.32 GB). I'm using a 3 TB machine. It was still showing errors with 10 GB of free space.

Although it hasn't finished downloading yet so I'm not totally convinced.

Same issue here:

Every 100-150 MB downloads are stopped.

Error popup is saying: Network is interrupted; error number is -3253.

It is the same for simultaneous downloads On or Off, just makes no difference.

Also it does not make a difference if I download music, movies or apps as long as they are hugh enough to exceed this 100 MB limit.

Internet Provider is T-Online (Deutsche Telekom),

connection 16000 DSL - thus, should be fast enough,

Router is a Speedport V504B.

OS is Version 10.7.5. and iTunes is the latest version.

HardDisc about 35-40% still free.

No clue what to do.

The support of "iTunesStore_Support@apple.com" just was to ask if I have the latest version of iTunes (yes, I have, and so I wrote in my inquiry mail - seems they haven't read it completely), to switch off simultaneous download (I did) and to link to this discussion. Thus, not really a big help.

gckanable Your solution worked for me (fingers crossed). I changed the DNS settings to Open DNS, no joy. I changed the Ethernet settings to simply "full duplex" and downloaded straight away.
Thanks for the heads up

I had this same issue and it ended up being a firewall on my router. Please look at your router firewall settings!

has anyone received this error when sending email? i have outlook for mac, and have received this message when sending email. they pile up and i have to reboot to send... says connection to server failed or dropped... huh? so not a techy, what am I missing?

Sad to say the problem still occurs in summer 2015. Every time there are a few apps to update one or more will fail to download. Yet others will download just fine. Just retrying the download works so clearly the settings are not at fault or why would it suddenly work fine with the same settings. The connection is likely reset at the Apple servers end IMHO.
