LFS263 / Lab 4.1: Cannot ssh as aarna into VM - Keyfiles?

Hi,
In the lab part of the course, section 4.1- I am supposed to ssh into the aarna account on the openstack VM on GCP.
I am using the keyfiles provided in this discussion: https://forum.linuxfoundation.org/discussion/856828/dont-have-the-ssh-credentials-needed-for-the-aarna-account
However, I get a "permission denied" error trying to log in using the following command:
ssh -i aarna.pem aarna@external_VM_IP_address
->Please help out here. Are the keyfiles still up to date?
Thanks & regards
Roberto
-----shell output----
ssh -i aarna.pem aarna@...
Permission denied (publickey,gssapi-keyex,gssapi-with-mic).

Addendum - please also see:
1) Tried the same from Putty using the .ppk file - Putty returns this:
Using username "aarna".
Server refused our key2) A verbose ssh output from my Linux machine below.

Hi,
this is SOLVED now - I imported the public key from the aarna.ppk file into the GCP, and appended the name "aarna" as comment, so the machine recognizes the user and the key. This now works.
