QSsl different behaviour in Linux and MacOS

enne9

Hello,
I developed an application using QSsl sockets. Now, everything works fine when the client runs in a Linux environment, while it crashes on MacOS.

This are the important LOCs in the client (unfortunately I cannot share much more):

m_clientSocket->addCaCertificates(":/resources/certificates/rootCA.crt");
m_clientSocket->setPeerVerifyMode(QSslSocket::VerifyPeer);

If I set QSslSocket::VerifyNone instead everything works fine also on Mac. I don't think it is a problem related to the certificate format since it works fine on Linux. The certificate is self-signed.

Capturing the traffic I found out that the TLS handshake finishes successfully, but right after the client sends a FIN message to the server. I think it is caused by something related to the certificate sent by the server, but I am not sure.
Is there some additional step required on MacOS I am not aware of?
Thanks

Hi,

Linux and macOS have two different backends hence the possible differences.

What version of Qt are you using ?
On what version of macOS ?

Can you provide a minimal compilable example that shows that behaviour ?
