Thanks for your answer.
So, i did what you said…
When i’m trying to go on mydomain.fr i’ve got an “The connection failed” because it transformed automatically to https… but if i force the http, i’m getting “The connection was reset” error, and seafile is still accessible on port 8080.
Is it good?
Subsidiary question: how do i get rid of fastcgi if it’s going to make me some trouble?
(Thanks again for your help , i’ll do next steps tomorrow! )
