NextCloud - 502 Bad Gateway

guillaume95240 · Feb 8th 2023

Hi all,

I'm gonna be mad, I still have "NextCloud - 502 Bad Gateway" on my webpage when I try to go to my NextCloud.

I use Swag also and I think this is the issue

Soma · Feb 9th 2023

You need to give more information than that.

How are you launching Nextcloud?

Which Guide did you follow to install/launch it?

guillaume95240 · Feb 10th 2023

So, if I summarize.

I have Nextcloud with the port 450:443 and the Databace, MariaDB: 3306:3306.

I have swag with the port 10443:443, SUBDOMAINS=wildcard, VALIDATION=duckdns and URL=xxx.duckdns.org.

All these port are published.

In my box, I set a NAP : Swag 10443:443. (the onlyone)

In Swag config, I have nextcloud.subdomain.org. I don't touch anything more.

In Nextcloud conig, i set

Quote

'trusted_domains' =>
array (
0 => 'nextcloud.xxx.duckdns.org'
1 => '192.168.1.90:450'
),
'trusted_proxies' =>
array (
0 => 'swag',
),
'overwrite.cli.url' => 'https://nextcloud.xxx.duckdns.org',
'overwritehost' => 'nextcloud.duckdns.org',
'overwriteprotocol' => 'https',
...
'dbhost' => '192.168.1.90',

'dbport' => '3306',

What' going wrong?

well first...

If you go to https://www.your-domain.duckdns.org

do you get the swag page secured with a padlock?

guillaume95240 · Feb 10th 2023

Exactly, my connection is secure.

My container Swag, Nextcloud, Nextclouddb looks working well in the logs..

Edit:

For Nextcloud : I have this : PHP Fatal error: Uncaught Error: Call to a member function getLogger() on null in /config/www/nextcloud/cron.php:192

OK, so it's not swag, it's working.

I've not seen that error... I'll try to look more into it a little bit, but a quick Google searched turned up this...

Cron.php / Uncaught Error: Call to a member function getLogger() on null

Still didn't answered this.

Post your YML but hide sensible DATA (password, email, domain) inside a codebox.

And, on config.php, your overwrite host is wrong.

The correct syntax is:

Code

'overwritehost' => 'nextcloud.xxx.duckdns.org', #change xxx with your domain

I tried several things but that's not clear it's not fixed yet..

I install all php7.4 applications.

I try: in /etc/php/7.4/fpm#, then nano php.ini and add apc.enable_cli=1.

When I try This:

Quote

sudo -u www-data php7.4 -f /srv/dev-disk-by-uuid-f676f90c-93f5-4fdb-888e-b29ffea004f8/appdata/nextcloud/config/www/nextcloud/cron.php

It says:

Quote

Cannot write into "config" directory!

This can usually be fixed by giving the web server write access to the config directory.

But, if you prefer to keep config.php file read only, set the option "config_is_read_only" to true in it.

I don't have ea-php7.4 for this commande: /usr/local/bin/ea-php74 for This

Do you have an idea or how can I resolve that?

Quote from Soma

Sorry it's a bit complicated because I follow multiple tutorial. we can that one one, but without command line and for subdomain using a French Youtuber.

And this is what is the problem.

Mixing things won't help in any way.

Quote from guillaume95240

When I try This:

You're using Linuxserver image and the user www-data doesn't exist in it.

The user Linuxserver uses in their images/containers is abc.

Quote from guillaume95240

I try: in /etc/php/7.4/fpm#, then nano php.ini and add apc.enable_cli=1.

Stop messing more things.

You don't have to installing nothing or edit php.ini.

The latest Linuxserver image doesn't even run on php7.4 anymore. It runs on php8.

With all the mess you have in there, better to clean up the system and start fresh.

And if you do start fresh, use a different password for the MYSQL_ROOT_PASSWORD.

Now, every reader knows it.

That was one of my question, php is now 8.2 but I didn't find it in my configuration, only 7.4. Is it normal or because it's the most stable version?

I can start a configuration, it's not the first time. How can I clean up? Just for Nextcloud? Remove the Stack, images, folder in appdata?

PHP 7.4 is used on the host by OMV.

PHP 8 exists inside the container.

They're 2 distinct things.

If you don't have any data there, yes.

After that is done, post the YML you used for SWAG, hiding sensible data and we'll continue.

guillaume95240 · Feb 10th 2023

Ok, so I didn't have any Nexcloud or Nexclouddb in Docker or Appdata.

My Swag stack, I iwll use the linux server image:

First make sure that the old folders are non-existant:

ls -al /srv/dev-disk-by-uuid-f676f90c-93f5-4fdb-888e-b29ffea004f8/appdata/

Make sure that the user ID 1000 is the one you want to own Nextcloud (I recall reading you used docker1 but don't see it anymore

id 1000

id docker1 # If you followed macom guide, you probably made this user but it doesn't mean it's user 1000.

Now copy/paste the code below and use it to deploy the STACK the way you feel better (with Portainer or docker-compose YML or with the openmediavault-compose)

Just don't forget to change the PASSWORD to something else

Code

version: "2"

 nextcloud:

After deployed, open a browser with https://IP_of_OMV:450 (accept the warning for insecure connection) and do the initial configuration of Nextcloud but take care of the DATA you enter on the screen:

On the "Create an admin account" section, write a name for the USER && PASSWORD that will be the ADMIN of Nextcloud (this USER has nothing to do with USERS on OMV. See it as a independent system):

Leave the "Data Folder" as it is:

On the "Configure the database" section, Select "MySQL/MariaDB" and write the fields with the info from the YML:

Database USER == root

Database PASS == <The password that you set on MYSQL_ROOT_PASSWORD>

Database name == nextcloud

Database host == nextclouddb # Instead of localhost

Click "Finish Setup"

After that, and it is installed, we'll go fo the rest.

I re-organize my other stack, and I use the admin account instead of auser one (which was in group root/admin/user, I will let it only user). So I got that;

Code

drwxr-xr-x 5 root root 49 Feb 10 12:47 .
drwxr-xr-x 7 root root 116 Feb 7 23:50 ..
drwxr-xr-x 2 admin users 22 Feb 10 12:47 duckdns
drwxr-xr-x 7 admin users 111 Feb 10 12:44 heimdall
drwxr-xr-x 11 admin users 4096 Feb 3 02:34 swag

I add the stack, just modify my password and change PUID.

i get an issue here,

Is root the issue? And ir should be admin? Or my network swag_default? Because all my container are in Swag_default?

Using HOST "admin" (id 998) is nonsense, in every aspects.

Docker is meant to run with unpriviledge users.

That is why a user with id => 1000 is the correct approach.

Quote from guillaume95240

Since I don't use SWAG outside of the Nextcloud YML, this issue never happens.

To fix it momentary and to simplify for now, bring down the STACK, delete the folders and edit the STACK, like this:

Code

version: "2"
services:
 nextcloud:
  image: lscr.io/linuxserver/nextcloud:latest
  container_name: nextcloud

Redeploy the stack.

guillaume95240 · Feb 10th 2023

Ok, I update the stacks, they are now with PUID 1000.

Code

drwxr-xr-x 7 root root 109 Feb 10 13:45 .
drwxr-xr-x 7 root root 116 Feb 7 23:50 ..
drwxr-xr-x 2 xxx users 22 Feb 10 12:47 duckdns
drwxr-xr-x 7 xxx users 111 Feb 10 12:44 heimdall
drwxr-xr-x 4 root root 32 Feb 10 13:45 nextcloud
drwxr-xr-x 4 xxx users 68 Feb 10 13:45 nextclouddb
drwxr-xr-x 11 xxx users 4096 Feb 3 02:34 swag

Still the same issue, it seems that not the network mais the account?

Code

Error while trying to create admin user: Failed to connect to the database: An exception occurred in the driver: SQLSTATE[HY000] [1045] Access denied for user 'root'@'nextcloud.nextcloud_default' (using password: YES)

Do I need to setup with the stacks with this?

- MYSQL_DATABASE=USER_DB_NAME #optional

- MYSQL_USER=MYSQL_USER #optional

- MYSQL_PASSWORD=DATABASE_PASSWORD #optional

or, do I already have an old database?

Soma · Feb 10th 2023

You need to start posting the outputs inside CODEBOX, and not on Quote, please.

Changing the owner of a STACK on an existing deployment won't change the existing folders.

They have to be deleted, and when the container is recreated, they will be made with the proper ownership.

So, first, post the output of the EDITED STACK (only hide the PASSW).

Then, the output of:

ls -al /srv/dev-disk-by-uuid-f676f90c-93f5-4fdb-888e-b29ffea004f8/appdata/nextclouddb

ls -al /srv/dev-disk-by-uuid-f676f90c-93f5-4fdb-888e-b29ffea004f8/appdata/nextcloud
