DNS randomly stops working then works again?

[railswrack]

New to OPNsense. So far everything has been working fine but I ran into an issue recently.

I was playing an online game and got disconnected due to a network connection issue. I checked my connection and it was still online. Then I went to google and it worked, but when I tried going to any other website it wouldn't load and would give me a DNS error.

Like 5 minutes later it started working again without me doing anything. Then a couple moments later it went out again. Happens on all my devices connected to my network at the same time.

No idea what would cause this or how to fix it from happening again?

Update: DNS still working, but I want to know what caused it to stop working and how to prevent this from happening again. When the DNS stopped working, it stopped working across all devices connected to my internet (LAN). Not using any VLANs.

(The only static IP I have on my LAN (192.168.*.169) is my main pc that's wired to my switch. Not sure why it keeps saying in the DHCPv4 log file that there is a duplicate dynamic and static leases present for it. Could it be IPV4 and IPV6 leases conflicting with each other? Not sure if this could be a cause for my DNS issue?)
