Unable to access weblogic console from none of the browser's after fresh installation of Oracle EBS 12.2

Error:

The Server is not able to service this request: [Socket:000445]Connection rejected, filter blocked Socket, weblogic.security.net.FilterException: [Security:090220]rule 2

              

                  

Cause:

In config.xml file <connection-filter-rule> was deny

cd $FMW_HOME/user_projects/domains/EBS_domain_TEST/config/

$vi config.xml file

<connection-filter-rule>ebsdev.oracle.com * * allow</connection-filter-rule>

   <connection-filter-rule>0.0.0.0/0 * * deny</connection-filter-rule>

Solution:

cd $FMW_HOME/user_projects/domains/EBS_domain_TEST/config/

Backup the config.xml file and change <connection-filter-rule> from deny to allow

Steps:

[applmgr@ebsdev config]$ cp config.xml config.xml_oirg

open config.xml file and search for deny and replace it by allow

[applmgr@ebsdev config]$ vi config..

<connection-filter-rule>ebsdev.oracle.com * * allow</connection-filter-rule>

   <connection-filter-rule>0.0.0.0/0 * * allow </connection-filter-rule>

Bounce the application services and try it
