Is the router IP dynamic or static; i.e. did it get its ip from the main router (i am just guessing this router is connected to your internat:wan router)?
If it received the IP from the main router then I woul not chnage it but try to set the HA address to match the 68…since you now have access to the HA machine you can try untill it works imho

Yes the router is connected to the modem and thats how it gets its internet wan.
I have been trying to change the HA ip address to match my routers. But then you asked to change the subnet as I will have to change that anyway to change HAs ip address.
The problem now is I get stuck at step 4 of the link you set.
A much easier solution would be to simply factory reset it, but i cant find answers on that, so im trying the ip address
lets go back to basics then
please send ip of router NOW (not sure if you changed it)<
pleqse send nmcli feedback from your HA
are you on discord? that would be much faster
Assuming you did not change the router …Try this after you connected to supervisor
nmcli> set ipv4.addresses 192.168.68.22/24
Probqby you need to restart the machine then
I found this to restart from scratch…
If you can rename the config folder, then restart … then you could afterwards copy bits and pieces back…repeating again that I have no experience so donot kill the messenger 
I read in other posts that it may reauire a cabled connection
Hard reset - Configuration - Home Assistant Community (home-assistant.io)
WDYM cabled connection and copy bits and pieces?
discord? I qm on a french keyboard and fingers hurt
haha go for it
I am not quite sure what you did and what is wrong, but the screenshots you’re providing says its URL is http://mari.local:8123
Did you ever try this?
yes and it doesnt work.
I have a new network provider and i have moved to a new router. and that is causing me issues with HAOS on odorid. other devices work fine
Managed to fix it guys.
Changed the router subnet. Logged back into HA. And set the new ip address.
In conclusion: when switching routers or network providers. Change the HA ip from static to dhcp. This way the the new router will be able to recognise the HA server.
Thank you to everyone who helped

Have a look at DHCP reservations in your router…
In that way you can leave everything on dhcp, but still they wil always get the same IP.
The big advantage is, it is managed in one place, no need to configure devices individually.
(and keep a backup of this list, just in case you get a new router 
)
Yes I’ll be using dhcp reservations from now on.
Static ip caused me enough problems haha.
You suggested way back to change the subnet and frankly I had no what they were. After looking into them today I changed it and it worked

This all sounds similar to what happened to me. I changed provider and Home Assistant didn’t appear in the list of devices. Probably because I made HA have a static IP, 192.168.1.75 on the router being 192.168.1.1
My new provider’s router is 192.168.178.1. I have tried reconnecting my HA-Green to my the old router and entered the static HA IP address. Nothing.
I have plugged a monitor and a keyboard into the HA-Green and everything looks good, DOS like screen, but I don’t know what to do from there.
Any suggestions? Please.
This the first time I’ve had to drop out of HAOS. So, just checking I understand what I’m supposed to do.
Enter “login”
Enter “nmcli connection show” → this will give me a list of connections.
Enter “nmcli con edit “Your Connection Name”” where my connection name is identified in the above?
Enter " * nmcli> set ipv4.addresses 192.168.1.10/24 Do you also want to set 'ipv4.method' to 'manual'? [yes]: " → this ipv4 address is the static ip?
- Set the dns server and local gateway while you’re here → As my NEW router is 192.168.178.1 the following ip addresses should be 192.168.178.254?
# nmcli> set ipv4.dns 192.168.1.254
# nmcli> set ipv4.gateway 192.168.1.254
# nmcli> save
# nmcli> quit
Sorry for belabouring this, I just want to get it right and and NOT be locked out.
Thank you.
MarkNo, gateway needs to be the router address 192.168.178.1
You can also use the same IP for DNS, or you could use an external DNS like 1.1.1.1 or 8.8.8.8
So I put in the following:
nmcli> set ipv4.addresses 192.168.1.10/24
It is now sitting at nmcli>
I didn’t get the following:
" Do you also want to set 'ipv4.method' to 'manual'? [yes]: "
Have I made a mistake or am I on the right track?
Sorry for the hand-holding. I swear that once I’m on track I be quiet (for a while).
