this is my httpd.conf file I tested reverse proxy without any virtual hosts in this first draft.

Where is the problem? SSL is working fine by the way that is not the problem.

#
# This configuration file reflects default settings for Apache HTTP Server.
#
# You may change these, but chances are that you may not need to.
#

#
# Timeout: The number of seconds before receives and sends time out.
#
Timeout 60

#
# KeepAlive: Whether or not to allow persistent connections (more than
# one request per connection). Set to "Off" to deactivate.
#
KeepAlive On

#
# MaxKeepAliveRequests: The maximum number of requests to allow
# during a persistent connection. Set to 0 to allow an unlimited amount.
# We recommend you leave this number high, for maximum performance.
#
MaxKeepAliveRequests 100

#
# KeepAliveTimeout: Number of seconds to wait for the next request from the
# same client on the same connection.
#
KeepAliveTimeout 5

#
# UseCanonicalName: Determines how Apache constructs self-referencing 
# URLs and the SERVER_NAME and SERVER_PORT variables.
# When set "Off", Apache will use the Hostname and Port supplied
# by the client.  When set "On", Apache will use the value of the
# ServerName directive.
#
UseCanonicalName Off

#
#h AccessFileName: The name of the file to look for in each directory
# for additional configuration directives.  See also the AllowOverride 
# directive.
#
AccessFileName .htaccess

#
# ServerTokens
# This directive configures what you return as the Server HTTP response
# Header. The default is 'Full' which sends information about the OS-Type
# and compiled in modules.
# Set to one of:  Full | OS | Minor | Minimal | Major | Prod
# where Full conveys the most information, and Prod the least.
#
ServerTokens Full

#
# Optionally add a line containing the server version and virtual host
# name to server-generated pages (internal error documents, FTP directory 
# listings, mod_status and mod_info output etc., but not CGI generated 
# documents or custom error documents).
# Set to "EMail" to also include a mailto: link to the ServerAdmin.
# Set to one of:  On | Off | EMail
#
ServerSignature On

#
# HostnameLookups: Log the names of clients or just their IP addresses
# e.g., www.apache.org (on) or 204.62.129.132 (off).
# The default is off because it'd be overall better for the net if people
# had to knowingly turn this feature on, since enabling it means that
# each client request will result in AT LEAST one lookup request to the
# nameserver.
#
HostnameLookups Off

#
# Set a timeout for how long the client may take to send the request header
# and body.
# The default for the headers is header=20-40,MinRate=500, which means wait
# for the first byte of headers for 20 seconds. If some data arrives,
# increase the timeout corresponding to a data rate of 500 bytes/s, but not
# above 40 seconds.
# The default for the request body is body=20,MinRate=500, which is the same
# but has no upper limit for the timeout.
# To disable, set to header=0 body=0

    Are there any related messages in the Apache httpd (error) log? – HBruijn Jun 30 '18 at 19:03
  • Oh yes, there are some segmentation errors. I tested the revers proxy with and without ssl. What can be the reason for this Segmentation Fault? The segmantation fault occures by every request – Jan Rosum Jul 1 '18 at 12:35
  • Are you getting any core files? – Andrew Henle Jul 2 '18 at 10:02
