QSslSocket error: Issuer certificate could not be found

Question

I am developing an application on Windows which should connect to a server. Therefore I implemented a QSslSocket.

After the execution of the connection method the sslSocket errorString sends

The issuer certificate of a locally looked up certificate could not be found. The root CA certificate is not trusted for this purpose.

The certificates are fine, but I couldn't explain why the connection isn't established. Does anybody has an idea how to fix that problem?

Answer 1

I had to ignore the SSL error. So call QSslSocket::ignoreSslErrors() inside the slot which is emitted by the signal sslErrors(QList<QSslError>).

Now it works fine.
