My YunoHost server

Hardware: VPS bought online
YunoHost version: 11.2.3
I have access to my server : Through SSH | through the webadmin
Are you in a special context or did you perform some particular tweaking on your YunoHost instance ? : No
If yes, please explain:
If your request is related to an app, specify its name and version: WordPress 6.2.2~ynh1

Description of my issue

I installed the WordPress application. All worked fine. I tried to change the configuration “Expected usage” under " PHP-FPM configuration". After saving the changes, the WordPress doent work anymore. It show an error 502 Gateway :

502 Bad Gateway
If you see this page, your connection with the server is working but the internal service providing this path is not responding.

I plan to migrate my blog from my actual shared hosting to my new VPS server. I had migrated all things when this error happened. No choice to uninstall WordPress and reinstall it. I tried again to change the PHP-FPM option (High), did the same thing. But i created a Yunohost backup before.

Thanks

Please cleanup the header of the message template.

You are the administrator. :wink: What is the status of the PHP8.2-FPM service? Its logs?

Sorry for the template, it’s my first time here.

The service PHP8.2-FPM is enabled and running fine (all services are OK). The log show only yesterday. Do you want that I try to change again the usage level of my WordPress app and check the logs after that ? I will do a backup of my YunoHost before (cause the restore fix the issue).

Sorry I can’t tell for your second issue.

Maybe the bug can come from a change in a configuration file (Nginx, PHP, etc)…

First time it happened, I did a fresh install of WordPress (for now i’m running a VPS test, this is not my prod website). Next time, I created a backup of YunoHost settings and WordPress app. I restored this backup when I got again the 502 error. I don’t know if its the WordPress restore or the settings restore that fixed the issue.

Hello.

I’ve tried the same thing with the application SnappyMail (2.28.4~ynh1) where the same PHP-FPM configuration is offered. Changed both options for Medium. The application return now a 502 bad gateway. Here is the log at the moment I have tried to change the settings :
