Hi, all! I am trying to connect to my https server using the example \nrf9160\https_client
The example itself works connects to google.com and receives a 200 response.
Problems begin when I try to connect to my server on port 443.
When connecting, BSD generates an error EOPNOTSUPP
And in the console I get:
connect () failed, err: 45
The code that I changed in the example:
err = getaddrinfo("my_site.com", NULL, &hints, &res);
if (err) {
printk("getaddrinfo() failed, err %d\n", errno);
return;
}
((struct sockaddr_in *)res->ai_addr)->sin_port = htons(HTTPS_PORT);
fd = socket(AF_INET, SOCK_STREAM, IPPROTO_TLS_1_2);
if (fd == -1) {
printk("Failed to open socket!\n");
goto clean_up;
}
/* Setup TLS socket options */
err = tls_setup(fd);
if (err) {
goto clean_up;
}
printk("Connecting to %s\n", "my_site.com");
err = connect(fd, res->ai_addr, sizeof(struct sockaddr_in));
HTTPS_PORT is 443
Since I do not understand certification well, I have questions:
1) Can I use the certificate that comes with the example?
2) Can I disable the certification chain when connecting to the server?
P.S.
“Let's encrypt authority” certificate is installed on the server
Many thanks!
