Webrequests failing in example wifi_webrequest.rs for pi pico w #3361

Open Argonlifesee opened 2 months ago

Argonlifesee commented 2 months ago

After pulling the newest version of this repo the example "wifi_webrequest.rs" for the pi pico w no longer properly makes the webrequest and fails to make it both as an https and http request. Sadly I cannot say in which version it exactly broke, I will add that as soon as I get a version to work again, will probably take it's time as I currently don't have alot of time.

Here is the output an excerpt of the example being run as an https request:

Any help as to why this happens is greatly appreciated

Hi, is this still faulty today? I had stability issues with worldtimeapi.org roughly in the timeframe you sent this issue. Testing their endpoints now seems to work fine. I have no rp2040 with wifi with me right now, so cannot test from that.
