Victron Dc to Dc charger sudden low voktage

[Lukefx]

Morning all.
I noticed my Victron 12/12/30 has really low input voltage yesterday and isn't charging, the solar is working fine as you can see on the screenshot.
I'm guessing a lose connection or a blown fuse, would that be case?
Any thoughts would be appreciated.

Exactly that, loose connection or burned fuse. Melted fuse holder?

Loose terminal?

Proceed with caution.

Start at the engine bay battery connection and start working back.

Post your findings on here. .

Seems it was aoose connection under the seat luckily. I checked and tightened everything under the bonnet and nothing, then removed the drivers seat and removed everything and replaced and tightened all the connections and it's back to normal. So luckily nothing broken or untoward that needs replacing.
