Suddenly I cant access OMV WebUI anymore . Login page shows but after successful Login, it just sends me back to the login page. I cant remember exactly when I successfully accessed it but not longer than 2 weeks ago.
/var/log/nginx/openmediavault-webgui_error.log
Bash
2020/01/07 12:51:01 [error] 20340#20340: *1 FastCGI sent in stderr: "PHP message: PHP Warning: session_start(): open(/var/lib/php/sessions/sess_opb9ari5lt27hdv5berp7h5fg1, O_RDWR) failed: Permission denied (13) in /usr/share/php/openmediavault/session.inc on line 43" while reading response header from upstream, client: ::ffff:127.0.0.1, server: openmediavault-webgui, request: "HEAD / HTTP/1.1", upstream: "fastcgi://unix:/var/run/php-fpm-openmediavault-webgui.sock:", host: "127.0.0.1:32244"

Disk and another services look fine to me. omv-firstaid and omv-mkconf nginx not fix the issue.
