[Troubleshoot Socket:000445] Connection Rejected, Filter Blocked Socket While Accessing EBS R12.2 WebLogic Console

Error:-

While accessing the WebLogic Admin console  http://<url>:7003/console reported with the following 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”

Root Cause:-

The error I encountered is due to WebLogic offers a concept called “connection filter“.  Connection filters provide network layer access control and allow the server(s) to block unwanted communication based on different criteria. 

You can check the WebLogic connector filter configuration under the config.xml file. 

Note: config.xml is a file that contains all the WebLogic configurations

In the above config.xml file, you can see that it is blocking the connection for 0.0.0.0/0 where 0.0.0.0/0 is nothing but public/private internet.

Note: Using Weblogic Connection filter you can also control access to particular IP

Solution:-

1) Open  the config.xml file

     cd $EBS_DOMAIN_HOME/config

2) Backup your config.xml file before making any changes

     eg: $ cp -R config.xml config.xml_bkp

3) Search for connection-filter-rule

4) Change the string “deny” to “allow”

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

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

5) Save the config.xml file & bounce the admin server

Now you will be able to access the WebLogic console :)
