Update problem

My frist problem is updating my Jetson Nano.
I try to update my Jetson Nano using sudo apt-get update its working but I receive this errors 2 times in update sesion

Hata{Error}:  28 https://repo.download.nvidia.com/jetson/common r32.4 InRelease
  'repo.download.nvidia.com' çözümlenemedi{No resolve}

Whats wrong? How can I resolve this problems?

That problem could be from outside of your system, but it could also be a DNS setup. If you web browse to somewhere common, such as http://www.google.com or http://www.nvidia.com, are you able to reach those sites?

Also, do you have any kind of router or firewall which might be blocking that domain?

I was check my router settings is not block any site or IP. I was ping this address, response time too big (>200ms).
I was try update and upgrade 4-5 times is working now but is download speed too slow (~345 Kb)

I’ll contact my ISSP about downloading speed.

Thanks for your help.
