error is on client side, so maybe your isp force you to use some proxy server...

I also always get 800 error on ES6710 and E8000, both on latest Samsung FW... haven't had a problem a month ago when downgrading an ES6300 (don't have that one anymore).
Could it be Samsung blocks your IP 46.4.199.222 in newer firmwares?

Yes, I believe somewhat like that they maybe blocked IP, because today tryed another 2 more diferents isp and at end the error is always same

btw when i used automatic DNS too and says I have last firmware... a bit strange...

Well, what can we do then?
Is it possible to just re-route TV's request to 46.4.199.222 in the router?
Or can we get the patched firmware (or any older fw) for download to update / downgrade via USB?

if your router supports it, yes

no

Just did a factory reset from service menu and tried from scratch but still 800 error.
I'm on ECPDEUC 2002 and it seems there's even a newer one available on Samsungs site: 2003.4
... I guess it won't fix that error 800 problem, right?
Can anybody with 2002 or higher reply who was able to download the SamyGo patched FW?
Is it just me/us or really Samsungs limitation???

Hi Arris69! Can you publish hyperlink (or links table) which TV assumed for firmware downloading and ip address of the server with yours firmwares? I want to play with 'hosts' file and the dnsmasq program for "re-route TV's request" on my Zyxel Keenetic Giga router.

play with hosts file makes just sense on tv.
if you play with dns, if tv requests
http://www.samsungotn.net dns answer shoud be CNAME infolink.samygo.tv
if you play with iptables and nat then reroute the traffic to 46.4.199.222
but no further support by me if you try to "hack around", thats why we made the server implementation, just set dns and let the tv make rest...
and if samsung coders really got the point how to make "secure" firmware updates all above won't help.
