Support Installation

Hi,

I am a beginner at Yunohost and I installed my server yesterday.
I created my first user and installed Roundcube but Yunohost does not work correctly.

I can not access to Roundcube and the user interface > 502 Bad Gateway !

I tried to restart the service php7.0-fpm and the computer but the situation remains the same.

More details about my installation here

I finally give up …
I reinstalled yunohost and this time use simple password. I do not know of there is a relationship but it worked
