utl_http.SET_AUTHENTICATION_FROM_WALLET(v_req, 'credential.name') it is giving network ACL error.

We are connecting EBS R12 with SCP cloud instance, using UTL_HTTP. when use direct authentication utl_http.set_authentication, it is working fine.

but when use utl_http.SET_AUTHENTICATION_FROM_WALLET(v_req, 'credential.name'), it is giving "ORA-24247: network access denied by access control list (ACL)". Already DBA given access BEGIN

DBMS_NETWORK_ACL_ADMIN.append_host_ace (

host => '*Oracle Cloud URL*',

ace => xs$ace_type(privilege_list => xs$name_list('RESOLVE'),

principal_name => 'APPS' ,

principal_type => xs_acl.ptype_db));

end; . Please confirm. any other action need to be done.
