Cannot use 4096 bit RSA keys for key-based authentication in web sessions

In case of web sessions, key-based authentication using 4096 bit RSA keys fails with error message: "Wrong signature."

As a temporary workaround, generate the key pair by using openssh 7.8p1-1 in the old format and specify 2048 bits length:

ssh-keygen -m PEM -t rsa -b  2048

(PEM specifies the old format)
