Can’t ssh into node

[Sankalpa Timilsina]

Hi the shown command doesn’t work when I try to ssh into node. The get_nodes() shows the following ssh command:

ssh -i /home/fabric/work/.ssh/fabric_key_silver -J sankalpatimilsina12_0049769586@bastion-1.fabric-testbed.net ubuntu@2001:400:a100:3030:f816:3eff:fe16:c90a

The key is in the correct location.

It throws:Permission denied (publickey,gssapi-keyex,gssapi-with-mic).
kex_exchange_identification: Connection closed by remote host

Thanks.

Worked after creating an SSH client configuration file and using that.
