Your cause could be external. Someone bumping a cable, loose power
socket to a network switch, failing network switch, network switch not
liking glitches on the mains, cleaning unplugging something to plug
their vacuum into.

Is everything on the UPS, computer and hub?
Server, monitor, hub, firewall, microwave modem.
Nothing else.
I'd also check all plugs and sockets are firm.
I was the one that did that. They are all in tight.
The hub is getting long the tooth. Maybe I should have that replaced
too.
What do you think of this one?

Sorry, unfamiliar with it.
I've had to replace network switches a few times when they spanned
between buildings. You could see the LEDs on one of the ports madly
blinking when it got damaged (see: "flapping"). Power cycling it would
reset things back to normal, but over time failures became permanent.
This hub is over 11 yeas old. I never was happy with it to start with.
Outside network cabling is vulnerable to things like somewhat-near
lighting, and wind blowing over it causing hight static electricity
voltages. And you can have mains wiring problems between buildings,
within a building, or even within a room (if it spans a phase) cause
problems with equipment joined together by network cabling.
Outside cabling does not affect the internal network. I
am able to RDP and AnyDesk into all the workstations
when this happens
