"Failed to connect to server" VNC brand new VM install

[lukeeexd]

Hi,

Doing a brand new VM install tried with debian, centos and ubuntu. After configuring it and selecting the ISO it shows as started but the console says https://i.imgur.com/XlACbrY.png I've tried chrome, firefox, on my phone and I've updated java


Any help is appreciated

hi,

can you tell us more?

* pveversion -v

* qm config VMID

* can other VMs be access normally?

does the VM keep running during this?

do you see any other error messages in the task log? (double click on an entry to see details)

Yes it stays running, tasklog is just full of this https://i.imgur.com/PSAehR2.png. This is a brand new VM the OS isnt installed because we can't see the setup because of the VNC not working

 

[oguz]

can you connect to the containers vnc?

i'm guessing this could be some network misconfiguration. maybe the vnc port is firewalled?

Containers are all CLI, Mhm it could be a firewall issue. Do you know which port the vnc uses?

https://pve.proxmox.com/wiki/Ports

 

[lukeeexd]

I dont think its a firewall issue tbh, proxmox firewall is not enabled, unless I need to enable it on the host with UFW ?

 

[oguz]

okay if the firewall is disabled and you didn't configure anything for that, probably it's not a firewall problem.


is this a cluster or a standalone node?

 

[lukeeexd]

Its standalone with 9 containers and this VM

 

[oguz]

okay.

do you have a self-signed https certificate installed? that could cause issues like this.

can you post the output of this command: cat /var/log/daemon.log | grep -E "(pveproxy|pvedaemon)"

 

[lukeeexd]

Yes, letsencrypt certbot and we use Cloudflare too if thats helpful. That command outputs a lot of info, anything in particular I should be looking for?

 

[lukeeexd]

Just going to the IP without the reverse proxy and it works https://i.imgur.com/X4k17Ui.png

 

[oguz]

okay.. can you post your nginx config?

maybe it's not using the correct certificate?

server {
    listen 443 ssl http2;
    server_name proxmox.REDACTED.gg;

    root /var/www/REDACTED;
    index index.php index.html index.htm;

    error_page 404 /404.html;
    error_page 500 502 503 504 /500.html;

    location / {
        proxy_pass https://10.0.0.1:8006;
        include proxy_params;
    }

    location ~ /\.ht {
        deny all;
    }

    include REDACTED.gg_ssl_config;
}

server {
    listen 80;
    server_name proxmox.REDACTED.gg;
    # Redirect all HTTP requests to HTTPS with a 301 Moved Permanently response.
    return 301 https://$host$request_uri;
}

 

[oguz]

could you verify that you see the same SSL certificate when you connect with vs. without nginx proxy?

 

[lukeeexd]

Connecting by just the IP it is not using a cert it says "not secure" when just going via IP

 

[oguz]

are you connecting like "https://your.ip.address.here:8006" ?

 

[lukeeexd]

Yes and it doesnt use the cert
