upgrade to 11 from 10 failed

[pilere]

following my previous closed issue about a but in renewal the ssl certificate, I did upgrade the version on seafile :

          hi @SkywalkerSpace I am sorry to dig this issue, but I am using the Latest docker version and it seems that the /scripts are not coming from version 11.0 ... what make it use the correct folder ?

image: seafileltd/seafile-mc:latest

following this message, I did change my docker-compose file

but end up with a 502 error. 502 Bad Gateway

and impossible to find any error log ... except nginx telling :

2024/05/29 17:27:05 [error] 272#272: *222 upstream prematurely closed connection while reading response header from upstream, client: 82.4.5.2, server: sf.domain.com, request: "GET /api2/repos/ HTTP/1.1", upstream: "http://127.0.0.1:8000/api2/repos/", host: "sf.domain.com"

I did redacted the domain

nothing to be seen in /opt/seafile/logs (the seafile.log shows 2024-05-29 17:07:46 start to serve on pipe client)

where can I search more ?
