I closed bpo-39787 "test_ssl and test_urllib2_localnet failing with new OpenSSL" as a duplicate of this issue. Copy of the message:

"""
test_ssl and test_urllib2_localnet are failing when Python is built against top-of-tree OpenSSL. I'm attaching the output of: `regrtest.py test_ssl test_urllib2_localnet -W`

The output is from a powerpc64le machine with Python 3.8.2+ (1bbb81b251bc) and OpenSSL master (db943f43a60d1b).

A git bisect showed the problems started with the following OpenSSL commit:

commit db943f43a60d1b5b1277e4b5317e8f288e7a0a3a

    Detect EOF while reading in libssl
    
    If we hit an EOF while reading in libssl then we will report an error
    back to the application (SSL_ERROR_SYSCALL) but errno will be 0. We add
    an error to the stack (which means we instead return SSL_ERROR_SSL) and
    therefore give a hint as to what went wrong.
    
    Contains a partial fix for #10880

There is a file attached which contains test failures like these ones:
