Proxmox GUI no longer working after subnet change - console & ssh working fine

[tgm]

I'm preparing for a major network upgrade to start using VLANs. I'm still in the early testing phase. When I change the IP subnet of the management interface, the GUI will no longer connect, but the console is still fine (expected) and SSH works with the new IP address. I get the error popup, "Login failed. Please try again". The IP was changed in /etc/hosts, /etc/network/interfaces, /etc/pve/corosync.conf, and /etc/corosync/corosync.conf. Everthing was rebooted in the test environment. So what am I missing?

since you mentioned corosync.conf, is this in a cluster? is the cluster quorate?
