What version of openssl does .Q.hg require? - kdb

Question

I am trying to use .Q.hg in kdb and I get the following error
q).Q.hg`$":https://www.google.com"
'conn. OS reports: Protocol not available
[0] .Q.hg`$":https://www.google.com"
^
q))
When I execute (-26!)[] I get the following output:
q).Q.hg`$":https://www.google.com"
'conn. OS reports: Protocol not available
[0] .Q.hg`$":https://www.google.com"
^
q))
I have downloaded different versions of openssl from the openssl website and built them from source, but nothing seems to work.
I have also downloaded the certificate as instructed on the kx website and defined the SSL_CA_CERT_FILE variables.
UPDATE:
output from (-26!)[]:
q))(-26!)[]
'Could not initialize openssl. Error was incompatible ssl version
[4] (-26!)[]

Output from .z.k:

As per kx docs OpenSSL 1.1 is not supported, you need to use a 1.0.x version
