No, you need to log on to your new router - it should have a GUI where you can see what is connected to it. That or use FING (an Android APP) as that will at least ID the Raspberry Pi.
Basically go to http://192.168.1.1 in a browser. Should ask for a login - and your new router will have come with a user/pass. Failing that - what is the make of the new router?
EDIT : Also noticed that you are looking for 192.168.68.93 but your router is giving out addresses in the 192.168.1.x range.
I’m guessing you’ve done nothing with the router and it’s running on default settings. Your HA won’t be visible unless it gets a 192.168.1.x address or your router uses the 192.168.68.x range.

Hum interesting …
So what should I do to get both of the IP adresses to match ?
If it is a DHCP issue (which i think it is), it is what @Neil_Brownlee said, log on to your router on http://192.168.1.1 and lookup the IP address in your router (by finding your mac address in the dhcp lease list). This will probably be an address in the 192.168.1.x range.
after that you will be able to log on to HA by using http://192.168.1.x:8123.
And not related to your issue, but on that same page on your router you can probably turn the lease into a reservation, which will prevent HA from changing IP while connected to this router.

Put a monitor directly on your RPi and see it in its own logs.

That screen will also have the ip address of the machine running HA. Like

Welcome to the Home Assistant command line.
System information
IPv4 addresses for enp2s0: 192.168.20.254/24
IPv6 addresses for enp2s0: 2404:4404:1000:1300:4b5c:fcb:c567:2afa/64, fe80::8528:35de:c280:2bda/64

this line being the relevant one
IPv4 addresses for enp2s0: 192.168.20.254/24
So that tells you what address to type into your browser to access HA.

I’m sorry guys I’m a real noob 
So I didn’t understand everything
I tried to plug the raspberry, to check the logs so I share with you the picture of what I have
It seems I have a different Ip now (but when I scan my network I still have the old one indicated that I shared with you)
and for some reason on the main dashboard command line I have 0 IP indicated (
Thank you for your help !
172.30.x.x and 172.29.x.x are typical IPs on a virtual network.
In this case it is probably the internal virtual network of docker.
Just like you have a network behind your router and then some public IP, so have the docker software. The public IP is just one of the internal IP. The one you can still access HA on.
Try
ha net info
Quite impossible, your old IP address is not reachable from your new IP range…
You can only scan 192.168.1.1-254(/24) so that excludes 192.168.68.93 
eth0 does not have an ip address. Are you sure it is plugged in to your network? That all cables are OK?
The RPi have to leds at the network cable connector.
When the RPi is powered on, then these should light up. One of them might be blinking, but there should be active still.
If you have no lights, then your connection between the switch/router and your RPi is not working and we are down to hardware fault then, which means cable or network card inside the RPi.
Hum that’s weird, I’m litterally plugged to my router ! 
I have this one :
Does anyone know how could I set up the wifi ?
Maybe when some equipment in my house fried, it frieds also the ethernet part on this ?
Thank you so much y’all for your help !
Verified it is really plugged in well?
Tried another port on the router?
You can also try another cable 
Does the router show any activity on the led of the port?
After you have exhausted other troubleshooting (as suggested by @aceindy) if you have another SD card, install raspberry pi OS and see if the ethernet then works.
The leds are hardware controlled and will come on as soon as the network card is initialized.
yes it’s perfectly plugged
I tried with other router and cables
And no activity shown in any of thoses tests
Don’t you think the ethernet port got fried too ?
If yes how can I set up the wifi on this product ?
So you recommend to do the set up over again with another SD card ?
I’m gonna try that yes
