Cannot Edit Workflow Mailer configuration

[big]

Hi,
R12.2.4

Workflow mailer does not start. When try to edit and configure cannot go ahead and go to step 4. I receive:
Failure of server APACHE bridge.
No backend server available for connection: timed out after 10 seconds or idempotent set to OFF or method not idempotent.

System work "well" and we can connecte and have no where else this message.



Thank you.
