Fatal error: Uncaught GuzzleHttp\Exception\RequestException: cURL error 51: gnutls_handshake() warning: The server name sent was not recognized (see http://curl.haxx.se/libcurl/c/libcurl- errors.html) in /home/vagrant/www/test/xxx/vendor/guzzlehttp/guzzle/src/Handler/CurlFactory.php:187

It runs correctly on my Alibaba Cloud server and runs as above on my virtual machine. I don’t know what is the cause

Solved, refer to (http://blog.csdn.net/sgwhp/ar...), it is a problem with PHP compilation:
First sudo apt-get install libcurl4-openssl-dev
Recompile and install the php curl library
Perfect solution
