#Feather sample Wifi client gets no response

I've been using Wireshark long enough to remember when it was Ethereal 😸

#

This is a pcap from the Feather doing the HTTP request. I don't see anything obviously wrong with it, but I wonder if I'm missing some small detail.

I tried updating with "Content-Length: 0" as a header, same result.

I'm completely puzzled by this. I ran the same curl tests that you did, and even in the absence of a Content-Length header, duckduckgo responded just fine. I have only one thing left to try. Can you let me know your public IP so I can set up a WireShark filter for it. Then I can run WireShark on my web server, watching for a connection from your end. I can just leave that running as long as necessary, and then have you test it both with curl and with the device you're trying to debug.
The curl command will be:

curl http://scruffy.org/

which will come back with a 301 response, but at least you should get something.
Once I know your IP, I'll get WireShark running so we can test this out.

BTW, said in best "Obi Wan Kenobi" voice: "Hmm. Ethereal. Now that's a name I haven't heard in a long time." 🙂

netcat can be useful for debugging such things as well

I'm really puzzled by it, too. But I really only posted it in case there was some difference in Arduino 2.2.1 or the latest Espressif board libraries. I am hoping someone else can test with an ESP32-S2 board and duplicate.

I'm using a VPN so IP address changes. I'll DM you my current IP.
