Get into https webpage

i’ve tried to get into webpage content, but receive an error message:

SSL_connect: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed

there is no problem to get into that page by web browser or curl. i’ve also run that code successfully on other domains like or https:// httpbin .org

here is the extract from my code:

code (unfortunately it doesn’t work online, so you should run it locally)

i’m don’t know how to fix it, i’m not good at ssl stuff.
could anyone help me?

The webpage does not open in my Chrome browser as well. Looks like it has a problem with certificate.

if i set ssl context to
context = OpenSSL::SSL::Context::Client.insecure

and add that to http/client
client =, tls: context)

i rid off the error message, but page is still inaccessible.
@status_code=400, @status_message="Bad Request"

and i don’t like using insecure method as a solution.

– edit
i’ve changed to a webserver with the valid certificate, but the only change is another error message:

Error reading socket: Connection reset by peer

code with changed server

there was an issue on local machine with openssl and homebrew. solution was simple: read the console messages :slight_smile:

below is a message from brew install crystal

A CA file has been bootstrapped using certificates from the SystemRoots
keychain. To add additional certificates (e.g. the certificates added in
the System keychain), place .pem files in

and run

openssl is keg-only, which means it was not symlinked into /usr/local,
because Apple has deprecated use of OpenSSL in favor of its own TLS and crypto libraries.

If you need to have openssl first in your PATH run:
echo 'export PATH="/usr/local/opt/openssl/bin:$PATH"' >> ~/.bash_profile

For pkg-config to find openssl you may need to set:
export PKG_CONFIG_PATH="/usr/local/opt/openssl/lib/pkgconfig"
