not able to access internet

[omi]

We have a local router that we use to provide internet access to our desktop Proxy server, which is configured with version 8.1.4/ec5affc9e41f1d79 (running kernel 6.5.11-8-pve). However, when I attempt to connect it via LAN to provide internet access, it does not work. i can see my ip addr 192.168.50.18
But I am unable to connect https://192.168.50.18:8006/ in any browser and below is the conf file of etc/network/interfaces if there any changes need to be done kindly assist then

auto lo
iface lo inet loopback

auto eno1
iface eno1 inet manual

auto vmbr0
iface vmbr0 inet static
address 192.168.50.18/32
gateway 192.168.50.1
bridge-ports eno1
bridge-stp off
bridge-fd 0
bridge-disable-mac-learning

Hey,

I assume with "desktop Proxy server" you mean your PVE host. Can you ping the router from your PVE host? And can you ping PVE from devices in your network?

address 192.168.50.18/32

Your CIDR should probably be 24 and not 32.

yes im working in a startup. We have two desktop servers one desktop server is working properly where proxmox is already been installed and running successfully and on another desktop server im trying to setup a new proxmox server so thast i can take backups of vms from first desktop server and i tried to ping 8.8.8.8 it gives error -
From 192.168.50.18 icmp_seq1 Destination Host Unreachable
kindly assist facing this issue from weeks!

Like already said, editing the /etc/network/interfaces and changing address 192.168.50.18/32 to address 192.168.50.18/24 and then a systemctl restart networking will probably fix it.

Some basic networking knowledge:
The "/32" of the "address 192.168.50.18/32" is the CIDR part and means the server is using a subnet mask of 255.255.255.255 which means that the server is running in a single IP subnet. So it can't communicate with any other hosts but only with itself, without additional routing.

Below image is my proxmox desktop server so basically u can see a white LAN wire is connected to my proxmox desktop server and there is no blinking there is no issue in the LAN wire i connected to another desktop kindly assist!

Did you fix the problem with the netmask as @Dunuin suggested? Do you have a specific reason for using /32? Usually in a setup you are describing and if you want to communicate with devices on your LAN you would not have /32. Why would you use a second PVE for backups, and how did you plan to do that? Or do you want to put them in a cluster and setup HA? In that case you'd need a qdevice[1] for quorum if you only have two nodes.
