I just tried to connect to my proxmox system, and found that while the login page loads it won't accept my username and password. It spins for a while, then says "Login failed. Please try again." I've cleared the cache, tried a private window, and tried a different browser that's never been used with PVE before. I've confirmed I'm on PAM authentication (and also tested with Proxmox Authentication Server). The password worked this morning, so I'm reasonably confident that's right.


OK, let's try SSH: nope. SSH to the host hangs without ever prompting for a password. The system shows as online at my router, and responds to a ping. Telnet to port 22 shows that SSH is listening, it's just not prompting for a password. I've confirmed I can ssh to the backup server, so the problem isn't entirely the laptop I'm using, although I won't rule out that it's a part of the problem.

This happened once before, and I ended up hard power cycling it. Obviously, I'd prefer to avoid that. Has anyone else seen this before? If so, did you find an answer?
 
No signal on the monitor, no reaction to the keyboard.

(Sorry I didn't include that initially... I've only just gotten home where I can physically check.)
