Network is unreachable: connect to listener on [::]:443

Of a sudden, I can no longer access the two Proxmos webs.
The versions are 1.9.

But I can both access in ssh.

With ssh,
I found that the /var/log/apache2/access.log.1 has much logs as the following.

[warn] (101) Network is unreachable: connect to listener on [::]: 443

The date is the access.log.1 is July 24.
And the access.log is same date, and was zero bytes.
I thought the web interface is not working from July 24.

How do I, and how to kick the web correct ?


I did not restart the machines yet.
After I restarted it, if the web is still not work,
I must start the container with ssh. I've never done it before.

vzctl start / stop 1xx;

Is the above correct? said so.

Other hand
The others 1.9 Proxmox has also access.log.1 and access.log. dated August 3.
The access.log file was zero bytes also the same.

Both "pveversion -v" were below.

pve-manager: 1.9-24 (pve-manager/1.9/6542)
running kernel: 2.6.32-6-pve
proxmox-ve-2.6.32: 1.9-47
pve-kernel-2.6.32-6-pve: 2.6.32-47
qemu-server: 1.1-32
pve-firmware: 1.0-14
libpve-storage-perl: 1.0-19
vncterm: 0.9-2
vzctl: 3.0.29-2pve1
vzdump: 1.2-16
vzprocps: 2.0.11-2
vzquota: 3.0.11-1
pve-qemu-kvm: 0.15.0-1
ksm-control-daemon: 1.0-6

Hello yugawara

The versions are 1.9.
Rather old - I´d make a reinstall of proxmox. Obviously you use (only?) containers. Save them first (to an extern media) by (set SAVEDIR and VZDIR (depends on you configuration - default local is /var/lib/vz) according to your environment, CTID is your container ID)

cp /etc/pve/openvz/* $SAVEDIR/. 
cp -av $VZDIR/private/$CTID $SAVEDIR/.
and restore them after reinstall by copying back. Do the same for the templates you use.

vzctl start / stop 1xx;
Is the above correct?

Yes - stop containers before saving as described above. Also useful to study

man vzctl

Thank you replay;

I can not re-install the production server. I scared.
Let me install 1.9 to a new machine, and test the restore.
Thanks again.

And about "an extern media";
does 1.9 suport usb memry or usb disk?

Is it like;
mount -t vfat /dev/sdX1 /BAKUPUSB"

I din't use them to the 1.9 befor
I have been using FTP backup for Containers.

I am in the dateceter.
I crashed and build another machine.
1.9 of receiving macine is ready.

>> cp /etc/pve/openvz/* $SAVEDIR/.

There is no /etc/pve/openvz.
In /etc/pve/, there are followings.

drwxr-xr-x 2 root root 4096 Mar 22 2012 .
drwxr-xr-x 78 root root 4096 Aug 15 01:19 ..

-rw-r--r-- 1 root root 26 Mar 22 2012 pve.cfg
-rw-r--r-- 1 root root 13 Mar 22 2012 qemu-server.cfg

Please advice me!

What I doing?

Is a self-response.

I went back to the house.
Fortunately, one machine of two, the screen came up after shutdown and start-up.

Then /etc/pve/openvz/ appeared.

Soon, I will do the remaining one. After making a backup with application.
Please close this issue, and thank you again..
