linux - How to set up apache running on separate system OL7 to present trac wiki project

I need to somehow set up apache to present a content from tracd running on separate server.

I used following config definition:

# LB VIP1 - TRAC definition 
#        ServerName tracwiki.com
        ServerAlias "IP of loadbalancer"
#        ServerPath "/project/"
DocumentRoot "/pkg/moip/data/apache/docs"   
    AllowOverride None
    Options None
    Require method GET HEAD POST
   RewriteRule ^/project_name/(.*) http://"IP of Application server":8000/project/$1 [L,P]
    LogLevel warn core:info
    ErrorLog /pkg/moip/logs/apache/error_TRAC.log
    CustomLog /pkg/moip/logs/apache/access_TRAC.log common
    Redirect /project          https://tracwiki.com/project
#    ProxyPreserveHost On
    ProxyPass /project         http://"IP of Application server":8000/project
    ProxyPassReverse /project  http://"IP of Application server":8000/project
    Include /pkg/moip/apps/apache/conf/extra/limits.conf *

Unfortunately I still get a same message "content not found". Firewall between servers is opened via port 8000 (in direction web server to application server). Tracdeamon is running well on application server.

Package Version:
Trac 1.2.3,
Genshi 0.7.1 (with speedups),
pysqlite 2.8.3,
Python 2.7.5 (default, Jul 3 2018, 06:28:28) [GCC 4.8.5 20150623 (Red Hat 4.8.5-28.0.1)],
setuptools 0.9.8,
SQLite 3.7.17,
Subversion 1.7.14 (r1542130)

I also installed "flup" to use ajp protocols instead of http, but unfortunately I couldn't manage to properly start a gateway:

[trac-scripts]$ Traceback (most recent call last):   File "/home/lcuser/trac-scripts/ajp_to_wsgi_gateway", line 36, in 
        from flup.server.ajp import WSGIServer   File "build/bdist.linux-x86_64/egg/flup/server/ajp.py", line 91, in    File "build/bdist.linux-x86_64/egg/flup/server/ajp_base.py", line 42, in  ImportError: No module named _thread

I would appreciate any help.
