Given the error is GNUTLS_E_INVALID_REQUEST, I guess it is failing
because some parameters are incorrect.  At first glance IV length for
AES-128-GCM seems to be correct (= 12), while the key length is a bit
longer (= 24).

I tried to reproduce it with qemu-user-static and a docker image from:
https://hub.docker.com/layers/multiarch/fedora/34-aarch64/images/sha256-0f4ec96493357cfb3465368d93094d54ecacdd39c1d7ce53d7e2ae843a55273b?context=explore
but couldn't.  Would it be possible to identify the point where the
error is returned?
