I cant set outbund requests configuration correctly, this returned a 500 code error?

Hi, greetings, im working with an CICD integration with Jenkins. For the communitacion between my webhook and pipeline jenkins y need to set in the Admin Area, the allowing requests to the local network from webhooks. Unfortunately, after i set my ip address where lives my Jenkins container and check the two input options, y receive an error 500.

Someone has before this problem? i attach some images of the procedure.

Greetings
