Newb: OMV 5: Suddenly can't reach my server... Help please...

Hi, I know this is an old setup but it's been running like a train so I've left it alone...

I have a RAID 5 setup using OMV5 serving my files accessed by SMB.

Usually this is trouble free but suddenly my Mac can't mount the OMV SMB share.

The web gui can't be reached.

The server will respond to a Ping:

I'm 99% sure that ssh access is enabled as I've used it before but this is what I get in my Mac Terminal:

ssh root@192.168.0.211
Unable to negotiate with 192.168.0.211 port 22: no matching key exchange method found. Their offer: diffie-hellman-group1-sha1

Can anyone help me past this?

I just got an email from the system looking for the Backup disk, which I had disconnected:

The system monitoring needs your attention.
Host:        openmediavault
Date:        Tue, 17 Sep 2024 16:47:55
Service:     mountpoint_srv_dev-disk-by-label-Backup
Event:       Status failed
Description: status failed (1) -- /srv/dev-disk-by-label-Backup is not a mountpoint
This triggered the monitoring system to: alert

Something is obviously running, I just can't reach it...

I Googled the ssh error above and ended up going round in circles...

This gets worse...Chatgtp got me past the encryption errors but now my root password isn't recognised.

Is there anything I can do?

Quote from raulfg3

bast aproach is: use a monitor & keyboard atached to your NAS and login on it, and use omv-firstaid to change root password.

Thanks. As soon as I find a VGA cable around here I'll try that. Won't I need any sort of a password to run omv-firstaid though...?
