Okay. Then my only suggestion is to comment out each additional entry until you find which one gets you a response from your isp.
Quick check, after making those changes did you reboot or release and rebind the red0 interface. Just changing the conf file doesn’t change anything once dhcpcd is running.
The commands to release and rebind the red0 interface, which is quicker than a reboot ,can be found in this thread
