Vaultwarden gives 502 bad gateway nginx after reboot

[fadelidou]

Hardware: VPS bought online
YunoHost version: 4.3.6.3 (stable).
Bitwarden version: 1.21.0~ynh1
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 ? : no

Description of my issue

Bitwarden was randomly noty accepting my master password. Each time, the problem was fixed after a server reboot.

After my last reboot, I now get this message when trying to access the login page:

502 bad gateway nginx

Tried rebooting a couple times. Always the same.

Update: seems like other apps also have this problem.

Il semble que plusieurs choses clochent avec mon Yunohost. ouf… comment régler tout ca?

En essayant la solution proposée qui est marquée dans la partie “Détails” de chaque service en erreur sur ce diagnostique ?

Commence par mysql, vaultwarden se base sans doute dessus.
