Loosing WAN connection continously

Hi forum
As a novice I'm looking for help to debug/identify my issue and confirm "correct" settings. My WAN connection has begun to drop out repeatedly - 5th time today. It has happened once before in the 1 - 2 weeks I've had OPNsense up and running. I haven't made any changes to my setup today (or in the last week or so). Running OPNsense vers. 23.1.3_4 on a Protectli.
I notice the "Router Advertisement Daemon" status changes to "OFF". One time I restarted it, the "Unbound DNS" service changed to "OFF". The service keeps turning "OFF". I'm inclined to believe my issue is connected to this service -but not sure at all.
The System Log File General shows the "Warning opnsense /usr/local/etc/rc.linkup: hcpd_radvd_configure(auto) found no suitable IPv6 address on igc1".
My ISP provides a dynamic IPv4 address - not sure if they support IPv6. My knowledge of best practice when it comes down to IPv6 is very limited.
IPv6 is not enabled in "Services/DHCPv6/Relay".
I've setup "Unbound DNS" and "DNS over TLS" using Quad9 as nameserver.
Admittedly I've enabled both the Quad9 IPv4 and IPv6 addresses.
In "Unbound/General" I've checked "IPv6 Link-Local/Register IPv6 link-local addresses".
In "Interfaces/WAN/" I had the "IPv6 Configuration Type" set to "DHCPv6".
I've setup floating firewalls to only allow DNS requests to "This firewall" and block other DNS request. Maybe "This firewall" should be replaced with "127.0.0.1"? See attached Billede1 (picture 1).
I've setup a Port Forwarding rule to redirect DNS requests to the local DNS server. Not sure if I should include port 853 here. See attached Billede2 (picture 2).
I'll contact my ISP to see if they had issues, but the modem indicates that everything should be fine.
PS: How do I insert an image? I get the icon and the "frames" but what then...?

I contacted my IPS to verify that everything "on their side" was OK. Turned out that the had changed the setup of the modem so it no longer was in bridge-mode. She told me that he modem had been like this for a while (not changed today), so I wonder if this will solve my issue.
I guess this could mess things up quite a bit - but I'd really appreciate if you have any comments / input to my setup etc.
