Hi.
That's not the hardware.
I just clear cashe and cookies in my chrome and it's works!
Check IP adresses - must be in same subnet. I.e. you must ping proxmox server from workstation.
Check you use HTTPS, not http
Clear cookies or try chrome's incognito (ctrl+shift+n)
Good luck.
I have same problem. Just install from proxmox-ve_3.0-0428106c-13.iso
I can connect by ssh, but web interface don`t work.
