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:
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
