Let's Encrypt installation fails with WSGI on Ubuntu 14 LTS

I'm trying to install SSL certificate with Let's encrypt on my VPS running Apache + WSGI.

I'm following guide: https://www.digitalocean.com/community/tutorials/how-to-secure-apache-with-let-s-encrypt-on-ubuntu-14-04

It works fine for all PHP sites, but i get an error when trying to install SSL for Django app. I think the problem is, that SSL cert conf is made as duplicate or currect conf file, so apache configtest fails and whole instalation is reverted:

command: certbot-auto --apache -d django.my-domain.cz

Created an SSL vhost at /etc/apache2/sites-available/my-domain.cz_crm-le-ssl.conf
Enabled Apache socache_shmcb module
Enabled Apache ssl module
Deploying Certificate to VirtualHost /etc/apache2/sites-available/my-domain.cz_crm-le-ssl.conf
Enabling available site: /etc/apache2/sites-available/my-domain.cz_crm-le-ssl.conf
Error while running apache2ctl configtest.
Action 'configtest' failed.
The Apache error log may have more information.

AH00526: Syntax error on line 26 of /etc/apache2/sites-enabled/my-domain.cz_crm.conf:
Name duplicates previous WSGI daemon definition.

Rolling back to previous server configuration...
Error while running apache2ctl configtest.
Action 'configtest' failed.
The Apache error log may have more information.

AH00526: Syntax error on line 26 of /etc/apache2/sites-enabled/my-domain.cz_crm.conf:
Name duplicates previous WSGI daemon definition.

Lines about WSGI config looks like:

WSGIDaemonProcess vkcrm python-path=/var/www/virtual/django/vkcrm:/var/www/virtual/django/lib/python3.4/site-packages
WSGIProcessGroup vkcrm
WSGIScriptAlias / /var/www/virtual/django/vkcrm/vkcrm/wsgi.py

Does anybody know how to fix installation process or my config about WSGI daemon? Thanks!
