When Let's Encrypt is on, alias /webmail did not work

I have the problem.
I have ispconfig 3.1 on debian 8 jessie.
When Let's Encrypt is on for any domain, alias /webmail did not work for all domain
When Let's Encrypt is off alias /webmail work for all domain.
I do not know what I'm doing wrong.
When Let's encrypt is on I have error for mydomain.com/webmail

Code:

The requested URL was not found on this server.

 

I edit roundcube.conf and work
