proxmox 8006 port is closed cant access web ui

[jishnuj]

I made some changes in network interface , after that cant access proxmox via web ui and ssh ( changes i made - i removed enp2s0 from vmbr0 and added vmbr1 and attached enp2s0 and put static ip),after that i edited the etc/network/interfaces file using ubuntu live cd . Now i can access proxmox through ssh but still web ui not working getting an error in web browser like connection refused , i checked status of 8006 via ssh but it shows port closed.


My current interfaces file

# network interface settings; autogenerated
# Please do NOT modify this file directly, unless you know what
# you're doing.
# If you want to manage parts of the network configuration manually,
# please utilize the 'source' or 'source-directory' directives to do
# PVE will preserve these directives, but will NOT read its network
# the PVE managed interfaces into external files!

hi,

did you change the IP address of the host?
if yes, then take a look here [0], you will have to edit some other files to make it work again, namely /etc/hosts and if you had a cluster defined on your host then take a look at the section for editing corosync configuration [1]

* is this node part of a cluster setup?

* what do you get when you run hostname -i
