Hello everyone / Bonsoir à tous

### My YunoHost server

**Hardware:** VPS bought online  
**YunoHost version:** 4.3.6.2 on Debian 10  
**I have access to my server :** Through SSH  
**Are you in a special context or did you perform some particular tweaking on your YunoHost instance ?** : yes  
**If yes, please explain:**  
I enabled 2fa for ssh according to this guide : [https://www.linode.com/docs/guides/how-to-use-one-time-passwords-for-two-factor-authentication-with-ssh-on-debian/](https://www.linode.com/docs/guides/how-to-use-one-time-passwords-for-two-factor-authentication-with-ssh-on-debian/)

### Description of my issue

Earlier this evening I started an update via the Admin GUI. A few system packages needed updates (if i remember correctly they were: yunohost-admin, moulinette and ssowat) No applications needed updating. I came back 1 or 2 hours after and noticed the server is unreachable via https. I tried a reboot with no success. I connected via SSH and noticed that nginx is not running and fails to start because of a timeout.

Here is what I tried:

- restarting the service:

```plaintext
$ sudo yunohost service restart nginx

Job for nginx.service failed because a timeout was exceeded.
See "systemctl status nginx.service" and "journalctl -xe" for details.
Warning: Could not execute the command 'systemctl restart nginx'

```

- checking the logs:

```plaintext
$ sudo journalctl -u nginx

Jan 26 22:39:18 mydomain.com systemd[1]: Starting A high performance web server and a reverse proxy server...
Jan 26 22:40:48 mydomain.com systemd[1]: nginx.service: Start-pre operation timed out. Terminating.
Jan 26 22:40:48 mydomain.com systemd[1]: nginx.service: Control process exited, code=killed, status=15/TERM
Jan 26 22:40:48 mydomain.com systemd[1]: nginx.service: Failed with result 'timeout'.
Jan 26 22:40:48 mydomain.com systemd[1]: Failed to start A high performance web server and a reverse proxy server.

```

- Tested the nginx config:

```plaintext
$ sudo nginx -t

nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

```

- retried the update from cli, but everything is up to date :

```plaintext
$ sudo yunohost tools update system

Info: Fetching available upgrades for system packages...
Info: Nothing to do. Everything is already up-to-date.
apps: 
system: 

```

- I tried to see if something else was not installed correctly, but everything seems fine :

```plaintext
$ sudo apt install --fix-broken

Reading package lists... Done
Building dependency tree       
Reading state information... Done
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

```

I’m at a loss as to how to continue. Does anyone have any ideas ?

Thanks in advance and have a nice evening / Merci d’avance et bonne soirée

Does it give any other information when you run the non-yunohost `service` command?

```auto
$ sudo service nginx start # or restart, of course, depending on current status
``

When I run either of them, there is no mention of 'start-pre' operations. You could have a look in the init-file at `/etc/init.d/nginx' if anything could be related (I don't have anything 'pre' there either).

* I tried to see if something else was not installed correctly, but everything seems fine :

```

```auto
[/quote]

You could try `sudo apt get reinstall nginx`.

Does diagnosis on the command line give any suggestions?
```

Hi wbk,

Thanks for your reply.

Here’s the output of the non-yunohost command:

```auto
$ sudo service nginx start
Job for nginx.service failed because a timeout was exceeded.
See "systemctl status nginx.service" and "journalctl -xe" for details.

```

Here is the service status info:

```auto
$ systemctl status nginx.service
● nginx.service - A high performance web server and a reverse proxy server
   Loaded: loaded (/lib/systemd/system/nginx.service; enabled; vendor preset: enabled)
   Active: failed (Result: timeout) since Sat 2022-01-29 16:58:23 CET; 3min 45s ago
     Docs: man:nginx(8)
  Process: 20219 ExecStartPre=/usr/sbin/nginx -t -q -g daemon on; master_process on; (code=killed, signal=TERM)

```

Here is what I find in journalctl:

```auto
$ sudo journalctl -xe | grep nginx
Jan 29 16:56:51 mydomain.com sudo[20195]: admin : TTY=pts/0 ; PWD=/home/admin ; USER=root ; COMMAND=/usr/sbin/service nginx start

-- A start job for unit nginx.service has begun execution.
Jan 29 16:58:23 mydomain.com systemd[1]: nginx.service: Start-pre operation timed out. Terminating.
Jan 29 16:58:23 mydomain.com systemd[1]: nginx.service: Control process exited, code=killed, status=15/TERM
-- An ExecStartPre= process belonging to unit nginx.service has exited.
Jan 29 16:58:23 mydomain.com systemd[1]: nginx.service: Failed with result 'timeout'.
-- The unit nginx.service has entered the 'failed' state with result 'timeout'.
-- Subject: A start job for unit nginx.service has failed
-- A start job for unit nginx.service has finished with a failure.

```

Diagnosis complains about ports and domains not reachable and the service not running:

```auto
[ERROR] Port 80 is not reachable from outside.
  - Exposing this port is needed for web features (service nginx)
  - To fix this issue, you most probably need to configure port forwarding on your internet router as described in https://yunohost.org/isp_box_config

[ERROR] Port 443 is not reachable from outside.
  - Exposing this port is needed for web features (service nginx)
  - To fix this issue, you most probably need to configure port forwarding on your internet router as described in https://yunohost.org/isp_box_config

=================================
Web (web)
=================================

[ERROR] Domain mydomain.com appears unreachable through HTTP from outside the local network.
  - Connection error: could not connect to the requested domain, it's very likely unreachable.

=================================
Services status check (services)
=================================

[ERROR] Service nginx is failed :(
  - You can try to restart the service, and if it doesn't work, have a look at the service logs in the webadmin (from the command line, you can do this with 'yunohost service restart nginx' and 'yunohost service log nginx').

```

I reinstalled nginx via sudo apt-get reinstall nginx and tried to start the service, but the same timeout occurs.

A priori, tu peux tout de même tenter de lancer un backup (avec les commandes yunohost) et tenter une restauration de ton serveur. Le fait que nginx soit éteint n’empèche pas le backup en général.

Si tu veux je te fais un 2ème VPS pour faciliter la transition.

Salut,

je suis navré si mon message a pu paraître courroucé… C’était plus un appel à l’aide pour pouvoir trouver une solution qui profite tant à d’autres qu’à moi face au problème rencontré.

J’ai lancé une commande `yunohost backup create`.

Ok pour un autre VPS si c’est possible. Merci encore pour la disponibilité, le temps passé et la qualité des services rendu par ARN.

Merci ljf et ARN.

Salut,

Démarrage d’un autre VPS…

**Via SSH :**  
connexion en admin@domaine.tld

`Sudo su` pour passer en root ! (indispensable)

1. Lancement d’un backup : `yunohost backup create`
2. Création de 2 fichiers :

- 20220207-131219.tar
- 20220207-131219.info.json

1. Transfert des 2 fichiers backup du 1er serveur vers le 2e : ([info ici](https://github.com/yunohost/doc/blob/master/pages/01.administrate/06.overview/10.backups/backup.md))

```auto
scp /home/yunohost.backup/archives/20220207-131219.info.json admin@xx.xxx.xxx.xxx:/home/yunohost.backup/archives/

```

```auto
scp /home/yunohost.backup/archives/20220207-131219.tar admin@xx.xxx.xxx.xxx:/home/yunohost.backup/archives/

```

1. Via l’interface admin : paramétrage des réglages de base du 2d VPS :

- création du nom de domaine
- changement du mot de passe
- réglage des dns (via [Gandi.net](http://Gandi.net)) et création du certificat **Let’s Encrypt**

1. Lancement du backup

Le début se déroule sans problème… Puis, problème avec Nginx…  
Avant la réinstallation de la 1ère application, un problème lié à Nginx a été indiqué (identique au problème sur le précédent serveur…) puis un message d’erreur est apparu en fin de l’install de chaque application… Enfin, en cliquant sur OK pour acter la non installation…

Aucune application installée… Mais, plus d’accès via la console visuelle de yunohost…

1. **Retour à l’accès SSH…**

```auto
sudo yunohost service restart nginx

```

```auto

```

1. Installation de iostat

```auto
sudo apt install sysstat

```

iostat

```auto

vda 54.24 3032.09 6146.41 41361817 83845284

```

Voilà… Retour à la case départ… Si ça peut aider à cerner le problème et contribuer à trouver la solution pour le résoudre. 🤯

Zblerg, I think if I was to try to debug this, I would maybe use `strace` but that’s a bit technical … (something like `strace -P $(pidof nginx)` while nginx is starting … Or maybe try to manually start `nginx`, maybe with a debug option if one exists

I read about this error and some guys talked about ‘nginx systemd service file’
