Hi, I reinstalled the PVE to 7.4, after many trys installation successful, however cannot open GUI either via Edge or Chrome. Before the machine had been running PVE 5.4 well in same network system with no such problem.
These days I tried many way to check following previous post mentioned cause. No way can resolve the problem. Even the SSH connection getting worse, now oftens the SSH response hang. P.S. I applied update to PVE 8.4 but problem still.
Here below the copy of status, any advices is appreciated.

Please upgrade or reinstall with the latest (and supported) PVE 8.4. I don't know what you tried or changes but can only tell you what appears to be wrong with what I see in your post.

192.168.6.191 is not the same as 192.168.6.193. Maybe change the first to match the latter? Also make sure the address is static and not in the DHCP range of your router.
You should also not comment out the address and gateway line, as that determines the IP address of Proxmox on that interface.
Make sure to reboot after changing all this. Afterwards, please show the output of ip a and cat /etc/hosts /etc/network/interfaces (in CODE-tags for readability).

Hi Leesteken, thanks for the reply. Following your advice, I modified the address firstly. No yet fixed. Here below the code:

Can you successfully ping -c1 192.168.6.1? Did you reserve/statically allocate 192.168.6.92 in router? Does your router have IP address 192.168.6.1? Is 192.168.6.92 outside of the DHCP-range of your router (or at least reserved)? Are you running Proxmox inside another hypervisor (Hyper-V, VirtualBox, VMware ESX(i)/Workstation)?

Yes ping successfully. IP 192.168.92 is now statically reserved from router (IP: 192.168.6.1) outside DHCP range. PVE runs from bootable disk.

Code: 
~# ping -c1 192.168.6.1

I guess it's your router that is blocking (or not forwarding) traffic but I don't know how to troubleshoot your device.

EDIT: This looks like a very similar issue: https://forum.proxmox.com/threads/unable-to-access-proxmox-web-interface-–-request-for-assistance.165571/post-766856

I did several tries, not work yet:
- Turn off the firewall on client laptop, not work. Either browser in safe mode.
- Connect laptop directly to PVE node with patchcord, IP address in same network, not work.
- Change network interface to another port on the PVE node, not work.
- Apt install Nginx, nginx service running, web access to port 8006 or 443, not work.
- Apt install Podman, service running, web access to port 9443, not work.
Its wierd seems no GUI service output. How can I further monitor the PVE GUI from shell? Or whether there is alternative GUI on node local monitor can use?
 
Out of curiosity what is the status of
Code: 
systemctl status pve-manager
Could also try
Code: 
wget 127.0.0.1:8006 --no-check-certificate
that would at least show you if proxmox is serving a page or not.
