Error 403, Service not available

    Hello I suddenly get the message Service not available. Error 403 on some websites.


    The Error.log says the following:


    [Sun Dec 01 00:24:54.644840 2019] [proxy:error] [pid 2991:tid 139722215069440] (2)No such file or directory: AH02454: FCGI: attempt to connect to Unix domain socket /run/php/php5.6-fpm-xxx.de.sock (xxxx.de) failed

    I am using i-mscp 1.5.3, Ubuntu 18.04 and php 7.1 (php -v)

    I deleted now the files under:


    /etc/apache2/sites-enabled/domain.de


    and run /var/imscp/engine/setup/imscp-reconfigure


    and it was working. But is think there was something not working with update from php 5.6 to 7.1
