No functional TLS backend was found error

[Rozerchik]

Hello. I have an application where user needs to authenticate via oAuth. And I get the following error: qt.network.ssl: No functional TLS backend was found.
So, after I read some posts on StackOverflow, I tried to add ssl v3 via the Qt Maintance tool and get this dlls to folder, where exe file is. But, unfortunately, this does not help. So, can you help me solve this issue. I'm using Qt 6.6.0, and ssl version 3.
Here is my build folder:

Also, here is output of qInfo() << "SSL: " << QSslSocket::sslLibraryBuildVersionString():

qt.network.ssl: No functional TLS backend was found
SSL:  ""
