Can't access GUI webpage

[Eingedi]

Hello,
I have no idea why, but for the past few days I can't access the webpage.
I tried "https" and "http" - says the same. "The webpage is not available. ERR_TIMED_OUT"
The PVE server itself is available, I can access and log onto it from the server itself or from putty, so it's just the web that doesn't work.

Maybe it has something to do with SSH keys? I've just added an SSH key to my backup server, so it won't need password every time it backs up to it. I am not sure if the problem occurred before or after I did it, just wondering if it has any effect.

Please help it's very urgent.
Thanks.

Edit:
I've tried:
- pveproxy --debug
- service pve-cluster restart
- pvecm updadecerts
- clearing cache/cookies

NONE solved the problem. HELP.

Hi,
the ssh-key has nothing to do with the webfrontend.

http don't work - you must access the gui with https and the port 8006!

Like
https://ip.of.pve.server:8006

[Eingedi]

Yea, I am using with https. still doesn't work.
I believe the problem happened after I updated the system.

Hi,
any helpfull output during reload the page?

tail -f /var/log/pveproxy/access.log

Do you have tried to clear the browser cache?

Or reload on Firefox with pressed shift, which also force an "real" relod.
Which kind of browser do you use?

Udo

 

[Eingedi]

Nothing appears when I type 'tail -f /var/log/pveproxy/access.log', even after reloading page.

I am using Chrome, tried clearing cookies and cache, didn't solve problem. Tried to access via explorer and firefox, also doesn't work.

Nothing appears when I type 'tail -f /var/log/pveproxy/access.log', even after reloading page.

In this case the client don't reloaded, or pveproxy doesn't work.

Is the port open?

netstat -an | grep 8006
tcp        0      0 0.0.0.0:8006            0.0.0.0:*               LISTEN

Does the client reach the host?

tcpdump -i vmbr0 port 8006

Udo

 

[Eingedi]

Well, seems like we've found the problem.

netstat -an |grep 8006tcp 0 0 0.0.0.0:8006 0.0.0.0:* LISTEN
tcp 208 0 10.0.0.251:8006 10.0.0.191:52399 CLOSE_WAIT
tcp 208 0 10.0.0.251:8006 10.0.0.191:52400 CLOSE_WAIT

tcpdump -l vmbr0 port 8006tcpdump: WARNING: eth0: no IPv4 address assigned
tcpdump: syntax error

How to fix this?

How to fix this?

Hi,
this error apear, because you use an small L instead an small I ( -i like interface).

But netstat show's connections - if 10.0.0.191 are your client-IP, then pveproxy is working and your client had an connection to the host.

any firewall rules? host / client
proxy-settings?

rules on the host:

iptables --list

Udo

 

[Eingedi]

Oh wow, that was dumb of me.

No proxy or firewall rules as far as i know.

iptables --list
Chain INPUT (policy ACCEPT)
target prot opt source destination


Chain FORWARD (policy ACCEPT)
target prot opt source destination


Chain OUTPUT (policy ACCEPT)
target prot opt source destination

help??

 

[manu]

What is the output of:
curl -s -k https://localhost:8006 | grep title

on your proxmox server ?

Please note you need to install the 'curl' package if needed.

You should get something like:

<title>Proxmox Virtual Environment</title>


If this curl command works, it means the web gui is active and able to process

 

[Eingedi]

Nothing happennes.

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

That is all that's shown.

 

[manu]

Again what is the output of

netstat -ltn | grep 8006

 

[Eingedi]

Hi,

netstat -ltn | grep 8006
tcp 0 0 0.0.0.0:8006 0.0.0.0:* LISTEN

 

[manu]

can you try that command on the proxmox server:

curl -s -k https://127.0.0.1:8006 | grep title

 

[Eingedi]

nothing

 

[manu]

This will be my last try, after which I advise you to reinstall
What is the output on the server

pvesh get nodes

 

[Eingedi]

reinstall? Won't it delete everything? I... think there must be some other way.

pvesh get nodes
200 OK

pvesh get nodes

I have a very similar issue. The only possible way to connect is (1.) local or (2.) SSH from local network.
I run some commands by SSH connection:
-firewall stopped:

# pve-firewall status

disabled/stopped

-netstat:

# netstat -apn | grep 8006

nothing

-tail:

# tail -f /var/log/pveproxy/access.log

nothing

-curl:

# curl -s -k https://localhost:8006 | grep title

nothing

-pvesh:

# pvesh get nodes

-bash: pvesh: command not found

-uname:

# uname -r

4.13.13-2-pve

Any different advise?

Hi,
you have damaged your installation!

How looks the output of

dpkg -l | grep pve
