How to use http_client or https_client to send a post message to my web server?

Hello!

I threw away the Sparkfun board and replaced it with a nRF9151DK board; I'm hoping to get it work now, after trying for a year.

I'm using SDK 2.6.1 and 2.8.0; the default is SDK 2.8.0.

My setup:
Updated Windows 11.
Onomondo SIM.

I built https_client from a sample and it worked; but, when I changed the URL to "">https://ptsv3.com," it stopped working, although the idea is to send an HTTP(S) post message to my web server, which includes a path and the receiver PHP program.

I did not include the build log or code because I could not post it; perhaps the post was too large, but a serial terminal image

Also, which library should I use to remove these errors?

*- error: unknown type name 'u32t'
*- error: unknown type name 'u8t'

With kind regards
