Issue/Introduction

 

We're running a CA Access Gateway (SPS) and when we try to reach the
server root url, then the CA Access Gateway (SPS) reports an error in
the browser :

  CA Access Gateway - Error Report
  Error Details
  Request URI: /
  Error Type: SPS Exception
  Error Code: VirtualHostNotFound
  Error Message: Virtual host is not properly configured. 

How can we fix that ?

 

Cause

 

Looking at the host file, we see that the host FQDN is bound to the
loopback interface instead of the public IP :

hosts :

  127.0.0.1          mysps.mydomain.com
  10.0.0.1           myhost

The default virtualhost is configured with the host FQDN
mysps.mydomain.com :

server.conf :

<VirtualHostDefaults>
        # default session scheme
        defaultsessionscheme="default"
        enablerewritecookiepath="no"
        enablerewritecookiedomain="no"
        enableproxypreservehost="no"
        filteroverridepreservehost="no"

        # specify the block size for request and response in KBs
        requestblocksize="4"
        responseblocksize="4"

        #TO-DO:  Define any session scheme mappings
        #<SessionSchemeMappings>
        #    user_agent_name=session_scheme_name
        #</SessionSchemeMappings>

        # Web Agent.conf
        <WebAgent>
                sminitfile="/opt/CA/secure-proxy/proxy-engine/conf/defaultagent/WebAgent.conf"
        </WebAgent>
</VirtualHostDefaults>

# Default Virtual Host
<VirtualHost name="default">
        #addresses="192.168.1.100"
        hostnames="mysps.mydomain.com"
        defaultsessionscheme="default"

        # specify the block size for request and response in KBs
        requestblocksize="4"
        responseblocksize="8"

        #The defaults can be overridden
        #not only for the Virtual Host
        #but for the WebAgent for that
        #virtual host as well
        #<WebAgent>
        #</WebAgent>
</VirtualHost>

Environment

 

CA Access Gateway (SPS) 12.8SP3 on RedHat 7;

 

Resolution

 

Modify the hosts file :

  From 

  127.0.0.1          mysps.mydomain.com
  10.0.0.1           myhost

  To
  
  127.0.0.1          localhost
  10.0.0.1           mysps.mydomain.com myhost

and restart CA Access Gateway (SPS) to solve this issue.
