I am trying to use the HTTPS_Client example but I am struggling to get it working. It returns 200 unmodified, which makes me think everything is working in terms of the board and sim set up. When I modify it, it no longer works. Specifically, I am trying to reach a server I am hosting locally and tunneling to the web using the service Ngrok.
I am changing the HTTPS Hostname, and the certificate to match the one the Ngrok link needs. But when I send a push request, I get the following output:
+CEREG: 5,"2D51","02D26916",7,,,"00001010","11000001"
Network connectivity established and IP address assigned

Ngrok gives no indication it received anything and does not forward anything to my local server
Below are all the modifications to the HTTPS client sample I made:
In Kconfig:
changed HTTPS_HOSTNAME to:
string "HTTPS hostname"
default "684742f5075a.ngrok-free.app"
In main
modified certificate:
static const char cert[] =
#include "ngrokcert.pem.inc"
In CMakeLists.txt:
Changed the name of the certificate file to match
generate_inc_file_for_target(
app
cert/ngrokcert.pem
${gen_dir}/ngrokcert.pem.inc
