DNS Reflection Issues | Pterodactyl® | Page 1

I am having trouble fixing the reflection issues. When I am able to see the domain working for minecraft server, I am now unable to access the panel.
I changed my /etc/hosts to

::1             localhost ip6-localhost ip6-loopback
ff02::1         ip6-allnodes
ff02::2         ip6-allrouters
# --- BEGIN PVE ---
192.168.1.44 pterodactylubuntu.local pterodactylubuntu ptepanel.[domain].com bozos.[domain].com
# --- END PVE ---

I'm not sure how to debug it from here as I have made sure my dns records are correct and configurations.
I checked the logs files and the systemctl all seem correct.

You're going to need to provide actual errors. " I am now unable to access the panel." doean't help anyone help you

I have been getting
root@pterodactylubuntu:~# sudo tail -f /var/log/nginx/pterodactyl.app-error.log

But I was previously able to get it to work regardless of this error. 

I tried

sudo chmod -R 777 /var/www/pterodactyl/storage
sudo chmod -R 777 /var/www/pterodactyl/bootstrap/cache

but doesn't seem to fix the permission issue

Your Panel file permissions are incorrect. You skipped or made a mistake with the chown user:group command. This is covered in our installation guide here: https://pterodactyl.io/panel/1.0/getting_started.html#set-permissions
Remember to also chmod your storage with cd /var/www/pterodactyl/ && chmod -R 755 storage/* bootstrap/cache/

rustic oriole Mar 7, 2025, 6:13 AM

#

after running that command, I get

That's all the exact same text, with no timestamps

Are you sure that's not the same error entry?

rustic oriole Mar 7, 2025, 6:15 AM

#

even though I run the chmod command and giving it permission, it doesn't seem to solve the permission issue.

#

oh, that may be possible.

inner trellis Mar 7, 2025, 6:16 AM

#

Again, what's your actual error preventing you from reaching the panel
What are you trying to look for in the webserver logs

rustic oriole Mar 7, 2025, 6:17 AM

#

I'm not entirely sure. what other logs can I check to figure out why my panel can't be accessible now?

inner trellis Mar 7, 2025, 6:18 AM

#

Literally just your browser error
There won't be any logs on your machine if your browser can't reach your machine in the first place

#

Aka how are you determining you can't reach your panel

rustic oriole Mar 7, 2025, 6:19 AM

#

oh.
Hmmm… can't reach this page
ptepanel.[domain].com refused to connect.

inner trellis Mar 7, 2025, 6:19 AM

#

Check your nginx status, firewall and routing

rustic oriole Mar 7, 2025, 6:25 AM

#

I have to make port 8080 is accessible right? because thats for the panel

inner trellis Mar 7, 2025, 6:26 AM

#

Nope
8080 is wings default

Panel is plain old regular http/s ports

rustic oriole Mar 7, 2025, 6:33 AM

#

I debugged it to the point where I noticed that I can run the laravel frontend for the panel in port 8000 locally, but on port 80, I can't access it. is there any logs file I can look at more?

#

It seems port 80, port 443 is timing out according to port scanner.

#

my laravel log is showing this at the moment

📎 message.txt

inner trellis Mar 7, 2025, 6:37 AM

#

None of that is useful
The useful part is 76 lines above that

rustic oriole Mar 7, 2025, 6:38 AM

#

Is this better?

📎 message.txt

inner trellis Mar 7, 2025, 6:38 AM

#

But there won't be anything of use in your laravel log if nothing is reaching your panel

#

That's just your panel failing to reach wings

Solve your browser reaching your panel first. They are likely related

It seems I am able to access through curl but just not the web browser.

Is this correct thinking?

inner trellis Mar 7, 2025, 6:52 AM

#

That's your ptero machine reaching your panel
Doesn't help that much when your issue is your browser reaching your panel

#

Timeouts and conn refused are either firewall, routing or webserver issues

rustic oriole Mar 7, 2025, 7:09 AM

#

Yeah, thats correct intuition. now the panel is working. I had to port forward to 80 and 443.
