The Teensy 4.1 IMHO does not have enough Ethernet support on the forum. I hope that as it matures the community will have more help as I have yet to receive a single reply on my post below:

I have found the following library to be useful if you need to create a webserver.

HTML:
 https://github.com/khoih-prog/EthernetWebServer

To use it, you will need to make the following changes:

1) Install library "functional-vlpp"

2) In Stream.h located at C:\Program Files (x86)\Arduino\hardware\teensy\avr\cores\teensy4\Stream.h

Change from private to public.
Code:
char read_error;

3) Also, make the changes below in your code

Code:
#define USE_ETHERNET          false //true
//....
//....
#define USE_CUSTOM_ETHERNET       true //false

  #elif USE_CUSTOM_ETHERNET
      //#include "Ethernet_XYZ.h"
     //#include "EthernetENC.h"
    #include "NativeEthernet.h"

I hope this will be of help.
