WebServer not functioning on Teensy 4.1 about ethernetwebserver HOT 4 CLOSED

Hi

Thanks for using the library.

I suggest you start with the working and more complex Server examples as follows, I just tested OK and running reliably. Then modify then according to your requirements.

We're sorry We certainly don't have time to spend on your issue, unless you use those examples and prove they're not working.

2. WebServer_NativeEthernet

from ethernetwebserver.

Hey,

I can confirm the above issue on a Teensy 4.1 using the AdvancedWebserverExample.
The Teensy does not accept any connections but is running / prints the heartbeats.
As a difference to @MoosKarneval181, Ethernet.localIP() is always 0.0.0.0, whether static IP or DHCP.
I'm using Arduino 1.8.16, Teensyduino 1.55, and I have applied the patches necessary for the library.

Interestingly, it works on a different PC with Arduino 1.8.15 and Teensyduino 1.54.
I have already tried a fresh install of Arduino 1.8.16 and patching only Stream.h manually (in case that the patches are out-of-date...).
Please let me know how we can debug this.

I would actually like to use the library with platformio but there I run into the same issue.
I hope that finding out what the issue is will help fixing it there as well.

Best regards
Moritz

I suggest you first trying the better QNEthernet instead of NativeEthernet library.

I've just tested and added support to UPnP_Generic for Teeensy 4.1 + QNEthernet several hours ago.

The result in T41_QNEthernet_SimpleServer on TEENSY 4.1

Interestingly, it works on a different PC with Arduino 1.8.15 and Teensyduino 1.54.

I'm afraid only you can find out what is the issue, such as installation, missing files, etc.

Good Luck,

Thanks, it works with QNEthernet. With platformio as well... must be some issue with the current Arduino distribution or NativeEthernet then.
