Dying NAS??

[Akira]

So, logged onto my NAS yesterday to a frozen interface, couldn't connect to it via SSH or anything.
Rebooted it, green flashing lights for the drives and status but nothing, DSM web interface didn't come up and no SSH.
Rebooted again, the NAS showed temporarily in Synology Assistant but then vanished again.
Tried removing everything, RAM, drives, everything. Even with an unformatted drive it didn't show up in Synology Assistant.

Later on it randomly came back, stayed up for the rest of the day.
(When it came back docker was left in a stopped state which I then went on to start)
This morning I went to update my containers, they updated successfully but then the entire NAS locked up again and is back as it was yesterday.

Any ideas? Or am I looking at replacing it?
Connected all drives seperately (via an USB dock) to my laptop and SMART on all drives is absolutely fine.

If it is under warranty, open a support case with Synology - if out of warranty, looks like you are replacing it...

So, randomly came back again last night at 11:30 (ish) case open with Synology.
Nothing in the logs about anything. It does show failing to get an IP several times.
Which in itself makes no sense as it's statically assigned.

Just went again.
