503 error is due to your firewall blocking the proxy from connecting to backend server. proxy can connect backend now, hence 503 err is gone.

it was ok because i put it back to the normal DNS,
so you suggest to open the firewall for the proxy IP correct?
I am under attack again.

you have to open firewall for proxy in order to use it.
