Hi, Better to ask Synology forum. But the setting of the PHP Session directory should be : [https://kb.synology.com/en-vn/DSM/help/WebStation/application\_webserv\_php?version=7](https://kb.synology.com/en-vn/DSM/help/WebStation/application_webserv_php?version=7) ![image](https://www.dolibarr.org/forum/uploads/dolibarrorg/original/2X/1/1d98fb61a5069c40c5c403ca1fb7228e955d05de.png) Either you change the PHP Session directory setting to an existing directory or you create “/var/services/tmp” ---

Hi, I now have a 504 error code, I adapted the “Timeout” information but I still get the same error code. Would you have a solution? Thanks in advance ---

Having succeeded in my installation and if someone encounters the same problem as me, here is a modification to be made in addition to the “Timeout” already filled in ![Sans titre](https://www.dolibarr.org/forum/uploads/dolibarrorg/original/2X/4/44ee7a80d93af7eb80254220d4f086ced2aa8d69.jpeg) ---
