Installed a new proxmox 8.4.1 on a NUC8 and I'm stumped on this. I've installed several proxmox over the years and never encountered this.
if I connect by ip address it loads fast and everything works normal, no timeouts, no failures, and it's snappy. all good. I'd rather use hostname though so I can sign an SSL cert.
if I connect by hostname, short or FQDN, the login form loads very slow, and I get connection failed errors on some resources but not all, see image. I'm still using the default cert, that shouldn't matter, right?
Things I've checked:
- hosts and hostname file are correct
- ping resolves instantly and works by host and fqdn from client to proxmox, and proxmox to client. - no dns issue
- journalctl -f shows no error
- different browser or private mode behaves the same
- pvecm updatecerts no change
- systemctl restart pveproxy pvedaemon no change.
what's next to check?
