ansible ssh issue

Hello,

This is not an ansible issue to be frank but I am hoping someone here have seen it before and can offer some guidance. Note, I can manually ssh to the system, but ansible can’t.

I have a system that was previously working fine as a managed host. For the last two days though, ansible isn’t able to manage it. Ansible connection fails at setup stage. I have the ssh logs for both the client and the server, but can’t seem to glean the root cause from it. Hoping a second pair of eyes might pick what I am missing

Below are the client log and server logs consecutively. Does anything stand out from this logs?

Client:
