or better yet,

Who can i create an ACL for user Anonymous to have access to a specific hostname.

I wrote an article that shows how to create and maintain ACLs

https://www.experts-exchange.com/Database/Oracle/A_8429-How-to-use-Access-Control-Lists-in-Oracle.html


BEGIN
DBMS_NETWORK_ACL_ADMIN.create_acl(
            acl           => 'yourACL.xml',
            description   => 'your apex acl',
            principal     => 'ANONYMOUS',
            is_grant      => TRUE,
            privilege     => 'connect'
        );

        --- resolve might be optional for your use
        DBMS_NETWORK_ACL_ADMIN.add_privilege(
            acl         => 'yourACL.xml',
            principal   => 'ANONYMOUS',
            is_grant    => TRUE,
            privilege   => 'resolve'
        );

        --Assign these privileges to all hosts and all ports
        -- You can change the * to a specific host or set of hosts
        DBMS_NETWORK_ACL_ADMIN.assign_acl('yourACL.xml', '*');
        COMMIT;
end;


In your case though I think you want put the APEX schema as the principal, rather than ANONYMOUS.

Check the installation guide under "Enable Network Services"

when you say apex schema.

Do you mean the schema I am using apex with? (in my case cdc)

or, do you mean the users

apex_040000
apex_040200
apex_public_users

I've created the schema, i still cannot connect, oddly enough, when i run sql command from within apex, i can get the url.

please see below.

>>> I've created the schema, i still cannot connect


what schema did you create? How are you using this new schema in relation to this question?
Did you add your new schema as a principal to the same ACL as the apex owner?
