have you googled 'linux ssh how to login without password' ??
Weirdly that query didn’t return anything specific to Fedora guests (and only Fedora guests) not being able to use public key authentication to a specific subset of hosts while working perfectly fine on other hosts. I’m very familiar with public key authentication. As I stated I can ssh “without a password” from my Fedora computers to multiple different hosts just fine. And I can log in to the unifi gear “without a password” from multiple different machines so long as they are not running Fedora.
It turns out the one thing that had slipped my mind was the updated crypto policy in Fedora 33. Running "update-crypto-policies --set DEFAULT:FEDORA32” solved the issue for now. The next step is to figure out what was deprecated and see if I can override it in my .ssh/config file for the UniFi hosts rather than changing the crypto policy system-wide.
