VNC failing with SSH errors

[Bubbagump210]

This seems to have popped up on my cluster in the most recent upgrade. I am on 9.1.9 and I have been on 9 for a while. This is on every node of the cluster.

Errors that appears in the VNC window:
/root/.ssh/config line 6: Bad key types '+ssh-dss'.
/root/.ssh/config: terminating, 1 bad configuration options

/root/.ssh/config only has a single line - there is no line 6. Where do I start to fix this?

Hi, @Bubbagump210
Have you checked in all nodes?

Yes, this is on every node of the cluster.

My question might be unclear.
I meant checking /root/.ssh/config in all nodes.
Also, as someone else suggested in your other thread: files in /etc/ssh as well.
