#SSL_connect error
sage thorn
Is it your own server you're connecting to? It could be a server-sided issue where it's being disconnected
Maybe it's your SSL_CTX too, could you show me the options you've set (if you've set any)

im using the ws echo site because eventually i want to use websockets with this
but first, i want a simple https get request like this:
its not even getting to the SSL_write though heh

ive tried TLS_method() and a couple other methods
all with the same error

```c
#include <stdio.h>
#include <sys/types.h>
#include <sys/socket.h>
#include ...
ah goodness me
it took me A WHILE I'm sorry
int ssl_sockfd = SSL_get_fd(ssl);
```getting rid of this fixed it!!
azure vault
lmao im probably doing something terribly wrong
i dont often use C
im not a low level guy
azure vault
why
sage thorn
no idea I'll try finding out
sage thorn
hmm
sage thorn
I mean this is just weird. With my own HTTP client it seems to work fine for google.com and many others but not social.krunker.io and echo.websocket.org
sage thorn
scour forums?
most probably 😭
sage thorn
my god..
right it did say something about it supporting both HTTP & WS
SSL_set_tlsext_host_name should do it
azure vault
oop

SSL_set_tlsext_host_name(your_ssl_obj, "echo.websocket.org")
sage thorn
sorry for the ssl_write keep it the same
