Newbie network help, cannot connect locally or external

I recently installed HAOS in proxmox with the help of Proxmox VE Helper-Scripts. My proxmox rig is using wlan ( I know not ideal) , I was able to set it up to be able to connect to Proxmox, however cannot connect to any VMs or Containers. The /etc/interfaces/ is as follows:

auto lo
iface lo inet loopback
auto wlp2s0
iface wlp2s0 inet dhcp
wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

auto vmbr0
iface vmbr0 inet static
address 10.10.1.245/26
bridge-ports none
bridge-stp off
bridge-fd 0
post-up echo 1 > /proc/sys/net/ipv4/ip_forward

    post-up   iptables -t nat -A POSTROUTING -s '10.10.1.245/26’ -o wlp2s0 -j NETMAP --to '192.168.8.245/26’
    post-up   iptables -t nat -A PREROUTING  -d '192.168.8.245/26’ -j NETMAP --to '10.10.1.245/26'
    post-up   ip r add local '192.168.8.245/26’ dev wlp2s0
    post-up   iptables -t raw -I PREROUTING -i fwbr+ -j CT --zone 1
    post-down iptables -t nat -D PREROUTING  -d '192.168.8.245/26’ -j NETMAP --to '10.10.1.245/26’
    post-down iptables -t nat -D POSTROUTING -s '10.10.1.245/26’ -o wlp2s0 -j NETMAP --to '192.168.8.245/26’

    post down ip r del local '192.168.8.245/26’ dev wlp2s0
    post-down iptables -t raw -D PREROUTING -i fwbr+ -j CT --zone 1

Source /etc/network/interfaces.d/*

Dnsmasq was also set up, I am having issues understanding what I am doing wrong? Actual Local ip is 192.168.8.245/24. HAOS shows 10.10.1.137/24
Thanks for any help!

Hi, welcome to the forum!

In your Proxmox webUI, go to the HA VM and open the console: there you should see what IP address your HA has.

Also, did you try with http://homeassistant.local:8123 ?
