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. Errors:
/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?

Why not at least share that single line?
I'd check this

grep -sR "dss" /etc/ssh /root/.ssh /etc/pve

The .ssh/confg on each is

cat /root/.ssh/config
Ciphers aes128-ctr,aes192-ctr,aes256-ctr,aes128-gcm@openssh.com,aes256-gcm@openssh.com,chacha20-poly1305@openssh.com[/COD

and grep -sR "dss" /etc/ssh /root/.ssh returns nothing.

I suppose you can also check in /etc/pve. I edited the command above. You might want to edit your post too to make it more readable (message in code block) and not contain a needless quote. I should have asked sooner but when and where does this message pop up? Via SSH? Via the Shell/Console button?

I am realizing I am on the wrong path. It seems NoVNC is not working and the ssh error is from xterm.js. My real issue is NoVNC is failing with a 500 when I try to get into a VM/LXC and simply says failed when getting to a node. The pveproxy logs show as clean.
