I just updated my Proxmox, and now I cannot access the GUI (from my primary Windows machine). When I go to the Proxmox UI, I see:

I can ssh into 192.168.2.194. Also, looks like the VMs are working. Here's some other information that may help diagnose the issue:

Code: 
root@jupiter:~# cat /etc/network/interfaces
auto lo
iface lo inet loopback

iface enp0s31f6 inet manual

auto vmbr0
iface vmbr0 inet static
        address 192.168.2.194/24
        gateway 192.168.2.1
        bridge-ports enp0s31f6
        bridge-stp off
        bridge-fd 0

iface wlp2s0 inet manual
root@jupiter:~# cat /etc/hosts
127.0.0.1 localhost.localdomain localhost

Hi @arsaboo. Try to:
a) clear cache
b) disable all extensions
c) use incognito mode
d) if using windows - try running new chrome from sandbox
e) try different browser
f) examine Dev Tools console
g) search for this error online - there are more than a few hits

Good luck

In case you haven't already fixed the issue, what is the output of systemctl status pveproxy.service ? This service runs the server on port 8006.

OP said that the GUI access works on his Mac, only one particular PC/browser combination is "wonky". That would indicate to me that the PVE services are functioning fine.
