cURL error 56: OpenSSL SSL_read: No error information #4982

Description

@WouterFlorijn

I'm getting this error:

cURL error 56: OpenSSL SSL_read: No error information (see https://curl.haxx.se/libcurl/c/libcurl-errors.html)

When I google it, I literally get zero results. It appears nobody on earth ever ran into this error.

To be clear, there are other "versions" of this error, that also provide a description, like "SSL_ERROR_SYSCALL, errno 104".

I did this

Sent a request with mutual TLS through PHP (Guzzle library).

I expected the following

The request is successful.

curl/libcurl version
