random unraid crashing

[Psyonus]

I am hoping someone out there might have a theory for this:
I ran my unraid server since 2016, in that time I never had a single crash (non responsive/ locked up).
I installed pfsense on it's own hardware separate from the server 2 weeks ago. 
initially I set it all up and made a static ip for my server as I had done with the previous router. I tested my plex using 4g on my phone and bam 1st crash... I got it back up and tested again and again it crashed in exactly the same way. 
I decided to have my server accept a dhcp address and it then worked.

I have a plex docker, 2 game dockers and a Win10 vm.
the other day I was playing a game connected to one of my game dockers same as I had done for years I had no new containers no new vm just the same and it appeared to crash out of nowhere.
I was a bit frustrated at this point but persisted then this morning in prep to move things out of the closet to install a rack and run some cables I shut down my dockers and vm and it suddenly crashed again....I am going to revert to my old router and see if any crashes continue.
I run my server off a ups (decent one) so power was never an issue. 
if any ideas suddenly come to you I would love to hear it. I really want to use pfsense and it was nice not having my router open for my ISP to just look in whenever they want

I would personally start by scouring the logs, container logs, vm logs, and unraid logs, they usually have useful information to debug.
