Noob here ..!! I have recently installed ProxMox proxmox-ve_6.4-1. Looks like the installation is successful and it shows the screen with the URL to configure the server. But the URL is not accessible from any system.
Any help is appreciated. I have attached the ip a and cat /etc/hosts output.
Thank you,

what are the IP addresses of some of other systems in your network?
Can you ping from other system to PVE and vice-versa?
Can you ping between other systems?
What is the output of "cat /etc/network/interfaces"
What is the "ip r" output from PVE?
Can you ping the gateway?

what are the IP addresses of some of other systems in your network? -> 10.0.0.XX
Can you ping from other system to PVE and vice-versa? -> No I can not.
Can you ping between other systems? -> Yes I can form my Mac to another Linux machine
What is the output of "cat /etc/network/interfaces"
cat :etc:network:interface.JPG
What is the "ip r" output from PVE?
Ip r.jpg
Can you ping the gateway? -> Yes I can
 
Did you ping a DNS name or an IP address? Is the /24 network also configured on the other clients?
 
Did you make sure that the IP 10.0.0.30 is outside of the DHCP range of the gateway? I often read about traffic being blocked (or not router) when it overlaps.
 
Based on the fact that you can ping the gateway/router from PVE, but you cant ping between PVE and your other hosts, I agree with @leesteken - the culprit is likely your "smart" router.
As a test - run the cable directly between PVE and Mac/Linux, confirm proper communication. Put a simple non-managed switch where you can connect your hosts, or, as @leesteken said, try to play with moving IP outside of "protected" range of your router, or research your router config.

I Pinged the IP address. And /24 is not configured for other clients. I left that as-is when I was installing ProxMox. Do I have to change it? Thank you

I don't think it is out of the DHCP range of the gateway. Yes, I saw some articles too.
Thank you

Apologies, I can ping the router from other systems, not from PVE. Yes, let me try to run the cable directly or let me check the IP if it is in the protected range.
Thanks you.

What do you mean by this? Are the other clients configured as /24 or with a 255.255.255.0 netmask? Because if they are not the default for a 10 network would be /8 or 255.0.0.0. Having different netmasks on PVE vs the other machines could definitely cause the symptoms you are seeing.

ETA: I see @bbgeek17 was posting the same thing at the same time :)

Looks like other systems are configured with a 255.255.255.0 netmask. I do not have any other system that is hardwired through the ethernet cable so all the devices are over the wifi.
 
with a 255.255.255.0 netmask
is another way to write down /24

again, more than likely the configuration of your router expects something different on LAN interface vs Wifi.
Keep working on it, you should be able to ping the router first and foremost. Go over router settings, perhaps its a different subnet than you think.

What is configured on other clients? There has to be some subnet, configured or implied.
Execute "ip a" on your working Linux host.

Code:
root@nivya:~# ip a

Here it is from a working Linux host.
Thank you.

Sure, sounds good. Let me work on that. Looks like in the router settings netmask is 255.255.255.0 is set.
Thank you So much.
