No internet connection in chroot environment (customizing iso)

I want to customize a Ubuntu Desktop Iso and I have come that far, that I am in the chroot environment.

The problem is that I do not have Internet access in there to install anything.

I just can ping 8.8.8.8, but not www.google.com (for example). Everything goes through a proxy tho, so I made a file apt.conf in the apt folder of the chroot environment but still nothing happens.

I can not run lines like: sudo apt-get update -> It just says "W: Failed to Fetch over and over again"

Does somebody know a solution?
I followed these steps (to the part with the sed commands)

You have internet connection, as evidenced by the ping to 8.8.8.8. You just don't have DNS name resolution.

See the file /etc/resolv.conf in your root file system and copy it to the chroot environment.

Thank you for your help, I already tried this sudo cp -a /etc/resolv.conf ~/remastering/newfilesystem/etc/

I also tried using a simple network without any proxys instead. Still no connection to apt commands

In the chroot, try nslookup, host, dig or any program of your choice to verify that DNS resolution works.

Thanks, I did the asked commands but it says on both (nslookup host and dig): ;; connection timed out; no servers could be reached than I tried ping 8.8.8.8 for fun again and this worked with 10,2ms responsetime So weird!#
