Router Offline

[Adam.P]

I have OPNsense 19.1.4 set up with multi-wan on a small appliance. It has been in place and functioning great for quite a while, but last night it went offline and I wasn't on-site this morning so I walked users through power cycling the router and everything came back up.

I'm looking through the logs and the gateway log is the only one with relevant information:

All of these entries are from right after the router booted back up though. I've looked through:
https://docs.opnsense.org/manual/logging.html

There aren't any relevant entries anywhere from before it went down that I could find. Any idea where I should look to see what happened?

Thanks!
