Unable to access EBS Weblogic Admin console due to Socket:000445

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

WebLogic Server provides a default connection filter called weblogic.security.net.ConnectionFilterImpl. This default connection filter accepts all incoming connections except the ones defined in the Administration Console as a Connection filter rule. Custom connection filters may be written  by implementing the classes in the weblogic.security.net package.

Backup …/fs1/FMW_Home/user_projects/domains/EBS_domain/config/config.xml file and then edit the file to add a line within <security-configuration> </security-configuration> as shown below:

    <connection-filter-rule>0.0.0.0/0 * * deny</connection-filter-rule>
    <connection-logger-enabled>true</connection-logger-enabled>
    <node-manager-username>weblogic</node-manager-username>

to

    <connection-filter-rule><ip-or-cidr>/xx * * allow</connection-filter-rule>
    <connection-filter-rule>0.0.0.0/0 * * deny</connection-filter-rule>
    <connection-logger-enabled>true</connection-logger-enabled>
    <node-manager-username>weblogic</node-manager-username>

Type your machine [IP address]/32 or a CIDR range.

Restart admin server using adadminsrvctl.sh script.

Access WLS Admin console.
