Hi,
I would like to test a websocket connect over NB-IOT with the nRF9151DK. I started with the https_client example to do an https handshake with the server and then add the websocket feature.
Here are my modifications (host name and enable nb-iot) :

string "HTTPS hostname"
default "httpbin.org"

"POST /get" \
"HEAD / HTTP/1.1\r\n" \
"Host: " CONFIG_HTTPS_HOSTNAME ":" HTTPS_PORT "\r\n" \
"Connection: close\r\n\r\n"
The result is : connect() failed, err: 111 (please find the logs bellow)

The certificate is valid, I have checked.
I have tested without NB-IOT (LTE-M) enable and www.example.com (base hostname) also, same result : connect() failed, err: 111
Any help is welcomed,
Best regards,
Mallory.
