Hi guys

I just updated proxmox 6.3 to 6.4 and restarted my machine.
The machine restarted successfully, all the vm / lxc are running ok with no problems.
The only problem is that now i cant access the proxmox webgui.
Anyone faced the same problem or can help me solving this?

Thanks for your time.
Regards

is port 8006 open?
can you check the output of the following command:

Bash:
curl  -k https://localhost:8006 | grep title

Also the journalctl -f to see if there any error message

It always worked, i didnt edited anything in this machine since 2019..
Now i just updated and the webgui is not acessible.

Attention: 8006 TCP port is open since always.. (OVH Game open all tcp ports by default)

I have a lot services running in this machine (that are running with no problems or restrictions).
I cant just turn off the firewall.

It seems that we have the same issue.

You can try to run the following two commands and see if it works or not.
dhclient -r vmbr0
dhclient vmbro

If it works, I do not know why. I am also waiting for someone who knows about this.

No, thats not the same issue..
Your issue is easy to solve: link
My issue is different, i already have "touch /etc/cloud/cloud-init.disabled" and restarted the machine, but it is still not working.

Today i tried to reset iptables:
iptables -P INPUT ACCEPT
iptables -P FORWARD ACCEPT
iptables -P OUTPUT ACCEPT
iptables -t nat -F
iptables -t mangle -F
iptables -F
iptables -X


Didnt solved the problem.


Then i stopped proxmox firewall:
pve-firewall stop

Didnt solved the problem too.

I really dont know what is the problem, it was only after upgrading v6.3 to v6.4.

Hello Ips90,

Did you manage to fix your issue? I'm having the same issue after installation proxmox to my baremetal server.

Hello Ips90,

Did you manage to fix your issue? I'm having the same issue after installation proxmox to my baremetal server.
Did you read the full thread? :rolleyes:
Maybe there is a possible solution to your problem..
Your problem is not the same as mine.
Mine problem is after updating the proxmox v6.3 to v6.4, your problem is after installing proxmox.
Different things..

To my problem i already did what Staff Members said, but didnt solved my problem and until now there is no more feedback from them.
I'll probably have to reinstall proxmox and i will not update it anymore to avoid this kind of problems / bugs.
