Bonjour, suite à un wazo-upgrade nginx ne démarre plus.  
Du coup plus d’admiration, plus Wazo clients (smartphone, pc).

voici la sortie du error.log:  
2022/01/02 10:49:12 [emerg] 15268#15268: zero size shared memory zone “noauth”  
2022/01/02 11:20:14 [emerg] 19942#19942: “limit\_req\_zone” directive is not allowed here in /etc/nginx/nginx.conf:86  
2022/01/02 11:20:54 [emerg] 20194#20194: zero size shared memory zone “noauth”

très urgent, merci Sylvain.

Bonjour,

Il faut lire les changelog et breaking change avant les upgrade.

> **[Upgrade notes - Unified Communication Use Cases - Wazo Platform](https://wazo-platform.org/uc-doc/upgrade/upgrade_notes/)**

Ton erreur vient que tu n’as pas accepté les changements de la configuration nginx.

Sylvain
