So on Linux (Raspberry Pi) I get the following message on the terminal

SSL routines:ssl3_read_bytes:tlsv1 unrecognized name:../ssl/record/rec_layer_s3.c:1543:SSL alert number 112

This leads us to

which mentions that 112 is unrecognized_name(112).

When I run it through the Qualsys SSL checker

it does mention that

This site works only in browsers with SNI support.

so I'm guessing at the level that sslConnect is working it is not getting SNI right.


Now the good news is that this works (again Linux on a PI)

WebClient httpHead: ''


WebResponse(HTTP/1.1 404 Not Found
date: Tue, 30 Aug 2022 18:22:48 GMT
content-type: text/plain; charset=utf-8
content-length: 21
connection: keep-alive
strict-transport-security: max-age=15724800; includeSubDomains

Now we know that it should work because WebClient works, and it sounds like SNI is an issue.

SecureSocketStream sslConnect just calls self sslConnectTo: nil

And that leads us to the comment in sslConnectTo:

"Perform the SSL client handshake. This method uses all the common SocketStream methods to adhere to the various timeout/signalling settings of SocketStream. It only installs the SSL instance after the handshake is complete. If serverName is not nil, then try to use it for SNI."

So, if one modifies your code as above it seems to work

stream := SecureSocketStream openConnectionToHostNamed: '' port: 443.
stream sslConnectTo: ''.
stream binary.
stream halt.
stream close
