SSH suddenly not working? (alien.top)

I have two machines, one is Windows 11 and my server is running Debian 12. SSH has run fine on both machines up until recently. Whenever i try to SSH into my server, it will reject the password (which is undoubtedly correct), and after a few failed attempts it will give me an error that says "Permission denied (publickey,password)." I can SSH into the server completely fine on my other devices, so the problem has to lie within my Windows machine. Since I last used SSH, the only notable things that have happened were that I installed (and soon after uninstalled) the OpenSSH server for Windows, and yesterday an internet outage happened that left me without internet for a full day. This morning, the router was reset and I've ensured that both machines are connected.

If this is the wrong sub to be posting this on, I'd appreciate if someone were to kindly point me to a correct sub on which I could repost.

Check your logs /var/log/auth.log. You can pipe grep it to search by IP or just try to connect then quickly check. That might give you more insight that isn't being provided to the remote client (windows).

Doesn't seem like there are any logs.

Check storage if it’s full, if it cannot audit your login it won’t let you.
