FOUND A WAY TO RESOLVE THIS!
Add
cat /etc/modprobe.d/ipv6.conf
# Don't load ipv6 by default
alias net-pf-10 off
# uncommented
alias ipv6 off
# added
options ipv6 disable_ipv6=1
# this is needed for not loading ipv6 driver
blacklist ipv6
to turn off all IPv6 on the Raspi.
Than edit all the IPv6 out of your config file.

ipWhitelist: [
"192.168.0.92",
"192.168.0.1/24",
"127.0.0.1"
I still have the .92 in there from testing. It is not needed.
did a sudo reboot just for safe measure and now it all seems to be working as intended. No real idea what the actual issue was…but it is resolved. FINALLY! :)
